Let Your Yarn Determine Your Weaving Project

Let Your Yarn Determine Your Weaving Project

Yarn First – Project Second

It happens to the best of us. Weaver sees yarn. Weaver buys yarn. Weaver has no idea what to do with yarn.

We’ve all been there.

In fact, if you’re like me you have quite a stash of yarn that is sitting and waiting to be used! Skeins and cones that I picked up just because I liked the color or as souvenirs. So what happens when you find this amazing yarn, but you don’t have a project in mind? Have you ever thought about letting your yarn determine your weaving project?

Let’s go over how to create a weaving project around your yarn instead of the other way around.

Know Your Yarn

The first thing you need to do is determine what the yarn can be used for. You need to look at the size, fiber content, strength, color, and feel.

I go over finding your perfect warp yarn in THIS post so check that out if you’re wondering about whether your yarn will work as warp. Once you determine that, you can move on. 

Generally speaking almost anything can be used as weft, but not every weft is created equal. At least not for every weaving project.


Think about this in relation to the warp you are choosing. Perhaps you are using the same yarn as warp and weft, in either case, think about how your yarns will interact.

Your yarn size plays a really important part of the type of weaving that you are trying to create. Consider what type of weaving works well with the yarn you have. If your yarn is really thick, it might serve you best as a rug weft or couched onto the surface of your tapestry. Really thin yarns aren’t always ideal for tapestries unless you are weaving something intricate – unless you want to be weaving forever.

The yarn’s size can help you figure out what EPI you should use or at least start with for your sampling. Even if you didn’t purchase this yarn online, you can always check out the information for similar sized yarns to see what their recommended warp setts are as a good place to start. Hopefully you have the packaging or information stickers from the yarn you are wanting to use. This will tell you what size yarn you have. If you don’t know the size, then you can estimate an EPI to start with by figuring out the WPI.

I talk more about WPI in my weaving planning e-book! You can learn more about that by clicking on the image below!

What’s your yarn made of?

Since different materials have different things that they excel at, this is important to keep in mind. If you find yourself with a wool yarn, you probably won’t want to use it to make tea towels since the wool would take a long time to dry.

Some examples of types of fibers that you might want to use for common weaving projects:

Towels (fast drying) – Cotton and linen

Scarves (warm, drapes well) – Wool, Alpaca, Acrylic. A spring or early fall scarf might be made from cotton or cottolin instead because it’s lighter.

Rugs (holds up to heavy traffic) – Wool, Acrylic, Cotton (mostly as warp)

Tapestry – Cotton or linen warp and wool weft (wool dyes better than other yarn types)

That doesn’t mean you are stuck using these materials for these particular projects. For example, most of my tapestries are made with cotton and linen weft because I’m more interested in the material than the range of colors that I can get. So do whatever feels right, but keep in mind what may be the best fit.


yarn determine weaving - strength

How strong does your yarn need to be? If you’re using it as warp then it’s important that your yarn be strong in order to hold up to the tension it will be under. This is even more important if you are using it for your tapestry warp since it requires an even tighter tension than other weaving types. 

Even weft will need a certain level of strength especially if you are creating a functional weaving. Yarn that is easy to break isn’t ideal for rugs that are going to see a lot of traffic. They will be more likely to fall apart after some use.

Different fibers are going to have different strengths mostly due to the way they are spun and the properties of the material. For example, linen is a very strong yarn because the flax plant that is used to create it has long fibers. The longer the fibers are, the harder it will be for them to pull a part.

To test your yarn out you can hold it in each hand and pull! Do this a couple times like you can see above. If it breaks easily, it is most suitable for non-functional work or as an accent yarn.


yarn determine weaving - color

Color doesn’t play a huge role in the type of weaving you can create, but it might play a role in the type of weaving you want to create. You can play around with color combinations between your different yarns to create fun and interesting weaving projects. 

Try wrapping your yarns you want to use around a piece of card stock or cardboard for a super quick way to see how good they look together. You can even save this and put it in your yarn notebook or sketchbook for future reference. On that note, make sure to record your new yarn in your notebook so if you like it, you can remember where to get more!

You could also just have all your skeins/ cones next to each other for color reference, but wrapping them let’s you see your colors in the ratio that you will see them in your weaving. Also, it looks nice! (it’s the little things sometimes)


This can be as simple as holding the yarn.

Is it soft or scratchy?

This will help you to determine if your yarn is suitable for functional weavings like scarves and blankets or better off used on your woven wall hangings.

If you want to use it as a scarf then try rubbing it on your face and neck! Since this is where your scarf will be worn it’s important that it’s comfortable. Something to keep in mind is that some yarns will get softer after washing, so you might want to test it out after it’s been washed. Do this by either washing a woven sample or a few strands of the yarn. Some yarns get fuzzier and some get softer after being washed.

Another thing you can do is to squish the yarn between your fingers to get a feel for how tightly spun it is. Yarns that aren’t spun as tight and have more air in them tend to feel softer because they have some give. Looser spun yarns will compress more when you beat down on them and might even drape better.

The best way to test the drape of a yarn is to – you guessed it – create a sample. Drape is determined by the warp and weft material as well as the weave structure. But, a strand or two draped over your hand unwoven is better than nothing if you can’t weave up a sample.

Create a sample

yarn determine weaving

I’m sure you saw this coming…

Samples are an amazing learning tool that you can use as a new or more advanced weaver. I use them all the time!

Doing these samples can help you figure out certain things like if your yarn is going to shrink after washing it. Does it get softer after a few washes? How do your different yarns (if using more than 1) interact?

Create a sample and then put it through the ringer (or washer) and try it out in different scenarios to see if it holds up to what you want it to do.

This will help you to figure out what to do with your yarn because now you have a real life example of what it is or isn’t good for!

Make sure your sample is large enough to actually get some information out of it – at least 2 inches by 2 inches. Or make more than 1. That being said, if you have limited amounts of this yarn then multiple samples may not be the best option. You don’t want to use it all up before you can fully make something! In that case, prioritize what you need to know in order to get weaving.

You can check out my weaving planning post to learn more about shrinkage and my post about the importance of samples and what else they can teach you.

Once you have all of this information, the only thing left is to find your inspiration and start weaving! If you’re letting your yarn determine your weaving project then it’s very possible that the yarn itself is your inspiration! In that case – just make sure it will work first!

The Difference Between Weaving and Knitting Yarn

The Difference Between Weaving and Knitting Yarn

Yarn is yarn, right?


Well, not necessarily. 

While knitting/crochet and weaving yarn can sometimes be used interchangeably – there are notable differences. I already did a blog post on decoding weaving yarn sizes that you should check out if you are in the market for weaving yarn. That being said, it can be oh so tempting to stroll into your local craft or yarn store and pick up any fresh skein of yarn that catches your eye. Trust me, I often fight this temptation.

Yarn is just so beautiful.

Unfortunately, you can’t always use those yarns for weaving (at least not for warp). Really, the topic of knitting and crochet yarn is a whole new section of the yarn universe.

For the purpose of this post I will refer to yarn as either weaving or knitting yarn, but keep in mind that yarn that works for knitting should also work for crochet. For the record – I am not bias towards knitting over crochet (in fact I’m a much better crocheter than knitter!), but I had to choose one for the sake of readability and knitting won.

Let’s go down the yarn rabbit hole. 

knitting yarn


One of the most notable differences in the weaving vs knitting yarn discussion is that the sizing is so COMPLETELY different. 

The quick and dirty version of weaving yarn sizes is that weaving yarn sizes are categorized by fractions where the top of the fraction is the size and the bottom is the number of plies (think 8/4 cotton). These sizes vary depending on the material. 

Knitting yarn on the other hand is categorized by descriptions. They range from 0 (lace) to 7 (super bulky) and within these categories they are further categorized:  Chunky, Worsted, Sport, DK (Double Knit), Baby, Sock, Fingering, and Lace. 

Yarns are placed in these categories by measuring their WPI or Wraps Per Inch around a ruler. Due to this, generally speaking you can expect any yarn in their respective category to create the same amount of stitches if you use the same hook or needle. This makes using these yarns for knitting or crochet simple.

So what does that mean for weaving? 


Unfortunately, unlike weaving yarn, I don’t know of any knitting or crochet yarns that give you a recommended warp sett on the packaging or website. Normally when buying weaving yarn online you can look up the recommended warp sett or EPI that will tell you how many warps per inch you will need for balanced weave.

Don’t worry! There is a way.

I do highly recommend you check out the EPI post linked if you are brand new before moving on to comparing WPI in the next section! When it comes to weaving – EPI is way more important to planning your weaving than WPI. WPI mostly comes into play if you are looking at non-weaving yarns.

knitting yarn size

Comparing WPI

Now, just like most knitting yarns don’t automatically tell you the recommended EPI – most weaving yarns don’t automatically tell you the recommended WPI.

Luckily, there is an easy way to figure out a general WPI based on the information that is usually given.

All you have to do is multiply the recommended EPI by 2.

Let’s look at an example:

Weaving EPI x2 = Approximate WPI

My go to favorite sample warp yarn: 8/4 Cotton Rug Warp

Recommended warp sett (EPI) for balanced weave: 12-15 (this number comes from experience, but also from the website I purchased it from)

12 x 2 = 24

15 x 2 = 30

WPI = Approximately 24 – 30

If you then take that info and look at the charts HERE and HERE – then you can see that 8/4 cotton is similar to a category 1 knitting yarn or fingering/ sock weight.

This, of course, works the other way too.

Need help planning your weaving project? Stuck trying to figure out how much yarn you need? What the h&^$ is WPI? Check out my e-book!

weaving and knitting yarn


Weaving yarn tends to be much stronger than knitting and crochet yarn. This is because weaving requires the yarn to be consistently under high tension. 

Due to this, you might not always be able to use knitting yarns for your warp. 

They will still work well as weft, since anything can be weft.

So how do you know if it will work as warp? Besides reading the post I linked at the beginning!

You have to do the strength test. If you own the yarn then this is really easy. Just take the yarn in both hands and give it a really good tug. If it breaks easily? Weft only. If it takes a lot to break? Possibly ok as warp if you don’t need a lot of tension. Doesn’t break? Perfect.

If you don’t own the yarn then if you are lucky they yarn store employees will know about weaving and be able to help you determine if a specific yarn is strong enough to be under high tension. 

Employees not sure? You could always buy it anyway and if it breaks – it will still work for weft. 

So if you did happen to stroll into that yarn store and pick up some beautiful yarn – don’t worry! You can still find a way to use it in your weaving!

Knitting yarn also has a tendency to be stretchier than weaving yarn. This is because since it isn’t spun as tightly it has more energy and spring to it. This means that if you decide to use it for warp – once it is no longer under tension, your weaving could change. Each yarn could be different though – so it’s best to try it out first if you want to use it.

When in doubt, though, it is probably best to purchase yarn made for weaving – at least when it comes to your warp

yarn strength test


Is that a word? 

When yarn is spun commercially it often is spun with oils. These oils make it easier to spin and keep all the individual fibers neat and smooth.

A lot of weaving yarns maintain these oils even after they are put on the cone and shipped to your studio.

Why would they do that?!?

Smooth yarns that still have their oils on them can be easier to warp your loom with! This is especially true when your EPI is tight. This means all of your warp yarns will be closer together and if you are warping a floor/ table/ or rigid heddle loom then the dents will be smaller. Therefore, it is harder to pass warp through. If they are oiled up – well you get the picture. 

That doesn’t mean that the yarn will be oily to the touch though. So don’t feel like you have to go wash your hands immediately after handling it. 

It does mean that you will need to consider this when planning your weaving. While the oils make it easier to warp your loom – if you are weaving something that won’t be washed you might want to consider washing the yarn first. If you are weaving functional work then don’t worry – just wash it when it’s all said and done and it will “bloom” and fill out. 

Not all weaving yarns are like this – but some are.

Knitting yarns on the other hand, don’t share this oily characteristic. They aren’t inherently as smooth as weaving yarns – but that doesn’t mean that none of them are smooth. Just that there is a greater chance of them being fuzzy. 

So what does this all mean? It means that when you are purchasing yarn you have to be aware of what you are buying. It’s always a good idea to ask questions and when in doubt – make a sample!

Common Yarn Treatments & Specialty Yarns

Common Yarn Treatments & Specialty Yarns

Buying yarn can be a little overwhelming at times, especially if you are buying online. It helps to know about some of the different treatments and types of yarn that you might come across. Some of these are superficial, but most have real benefits that you might want to consider for your next weaving project!









Need help planning your weaving project? Stuck trying to figure out how much yarn you need? What the h&^$ is WPI? Check out my e-book!


Mercerized Yarn

yarn treatments - mercerization

When you are purchasing cotton yarn, you may come across cones that are labeled as “mercerized”, “pearl”, or “perle”. 

While pearl and perle are just different names for the same type of yarn, they both refer to the mercerization process that the cotton yarn goes through. They are descriptive names, because you can tell them a part from other cotton yarns by the shine that they have.

It’s not all superficial though.

Mercerization is a process that was first discovered in the 1800s and is achieved through submerging the fibers in sodium hydroxide for a few minutes at a time. They are then rinsed to neutralize the acid.

This treatment does a few things to change the fibers. Most notably it helps the yarn take in dye better. This means you can use less dye than if it wasn’t mercerized. The fiber also becomes stronger after treatment. 

One possible con of this technique is that it makes the yarn a little stiffer than it’s matte counterparts so it won’t drape quite as well – in case that’s what you are looking for. That doesn’t mean you can’t use it for scarves, but don’t expect it to hang like linen.

Superwash Yarn

This treatment relates to wool and most often – knitting wool yarns.

Wool is a protein fiber much like human hair. This means that at a microscopic level it has scales that can latch onto each other during the felting process.

Simply, felting occurs when heat and agitation are applied to wool. The heat opens up the scales and the agitation makes them stick together. Felting can also occur with a special barbed needle that manually attaches the fibers together.

Superwash yarn goes through a process to “descale” the yarn which allows the yarn to be washed without felting. If the fiber is smooth then the attachment cannot occur.

This washable attribute is achieved through either an acid wash (similar to mercerized cotton) or by applying a protective coating to the yarn.

It also allows for higher absorption of dye and makes it an overall smoother – albeit stretchier – yarn to work with.

The biggest benefit of this yarn treatment is seen if it used for functional work that is meant to be washed. Scarves, sweaters, and blankets could all benefit from superwash yarn.


Wetspun yarn is attributed to linen and the way that is is turned into yarn.

First, it’s important to understand what linen actually is. Linen comes from the flax plant and goes through a long rigorous process to become a strong and absorbent fiber that has incredible longevity.

During processing the flax fibers are separated into “tow” and “line” . The tow fibers are the short fibers of the flax plant that are used to make rough linen yarns and rope. The line fibers are longer and finer. They are used to make higher quality threads, yarns, and fabrics.

The line fibers are spun wet to further their smooth characteristics. Not only is wetspun linen smoother – but it’s also stronger. This makes it an ideal yarn to use for your warp.


Bouclé Yarn

This yarn is characterized by the small loops or curls that create a textured surface. They are created by spinning with different tensions on the different plies of yarn. When plying yarn, 2 or more “singles” or non-plied yarns are twisted together to create a stronger yarn.

Bouclé texture comes about when 1 single with less tension curls up around the tighter single.

The word bouclé can refer to both the yarn and the fabric made from it.

This type of yarn would be best used as weft as it probably won’t be strong enough for warp. You can always try it out though, if you really want to use it as the foundation for your weaving.

Slub Yarn

These yarns have intentional areas that are thicker than the rest of the yarn. This creates an interesting texture throughout the weaving. Previously, these larger areas were seen as imperfections, but now they are created on purpose for their texture.

Slub yarns also tend to be soft and absorbent so they work well when included in towels and blankets. The thinner areas of this yarn make it not as strong as evenly spun yarn. Therefore, it is not recommended to use slub yarn as warp.

Chenille Yarn

The name chenille comes from the french word for caterpillar – which is a great way to describe this yarn.

Chenille was first manufactured in the 70’s and is notable for it’s soft fuzzy texture. This type of yarn can be made from all different types of fibers – cotton, acrylic, and more. The yarn is made from a pile yarn and a core yarn that are twisted together. It can be either flat or tubular.


Unlike the silk that you are probably used to that is made with long silk fibers, silk noil is made from the shorter fibers. This creates a textured yarn and fabric that resembles cotton, but with the drape of silk. Due to the shorter fibers used it is not as strong as traditional silk, but it is still durable.

Silk noil is an easy to dye yarn that is less expensive than it’s shinier and smoother counterpart.


Roving isn’t really so much a type of yarn as it’s actually the precursor to yarn. It is the fluffy un-spun fiber that is eventually turned into the yarn that you know and love. Roving is usually wool, but it can also be other protein fibers or cellulose fibers as well. You can buy almost any fiber as roving to either spin into your own yarn or to incorporate as is into your Fiber Art. It is usually sold in long and narrow bundles in a variety of different colors.

Wool roving is also used when you are felting – both needle and wet felting.

That being said, roving has become very popular to use as a weft “yarn” especially when using techniques like soumak. It creates a soft – cloud like texture that is hard to mistake for anything else.

These are just some of the types of yarn that you might encounter when purchasing yarn!

When in doubt, it’s always a good idea to read the descriptions you can find on the website if you are trying to figure out the yarn’s characteristics.

Online Yarn Stores To Build Your Yarn Stash

Online Yarn Stores To Build Your Yarn Stash

Where to find the best places to purchase weaving yarn and other materials has been one of the most asked questions in every class and workshop that I have taught. Ideally, everyone would have a local yarn store (LYS as it is affectionately known) in their area, but some of us are not lucky enough to have a LYS in our area that sells weaving yarn.

Instead, we can browse the many great online yarn stores and order from all over the country and the world!

When I was at Virginia Commonwealth University (VCU) for undergrad in the Craft department, I was pretty spoiled when it came to materials.

Cabinets full of a wide range of different fibers in lots of colors.

I miss the yarn cabinet.

Even one yarn I fear I may never be able to find again.

Like most art students, after graduation I was stuck with the arduous task of starting up my own studio. This meant, primarily, purchasing materials.

I was at a loss.

The type of yarn that is best for weaving unfortunately was not what you could find in any regular craft store.

I wish.

So I get it.

I understand that ordering yarn online is not always ideal.

We want to feel the yarn!

That being said, sometimes that is the choice you have.

This post may contain affiliate links. If you purchase something through these links then I will receive a small commission that helps keep the blog going – at no extra cost to you! Please read our DISCLAIMER for more info. Thanks for the support!

Tip: Look out for yarn sample cards that you can purchase if you’re not in a hurry for something specific. They are a great way for you to be able to feel the yarn and see the available colors in person.

Thank you internet! 

Luckily, most online yarn stores know that it is not a perfect situation – so they offer a lot of useful information in regards to their yarns. Most of them also offer weaving tools and supplies as well. You can order yarn for your stash, plus looms, shuttles, beaters, pick-up sticks etc.!

So here are some of my favorite online yarn stores and I have included their brick and mortar locations in case they also happen to be your LYS (lucky you!) These are all stores where you can find yarns suitable for weaving- unlike the novelty yarns found at most craft stores.

Although, novelty yarns can make for interesting weft.

The Woolery


859 East Main Street, Suite 1A. Frankfort, Kentucky 40601

The Woolery is one of my favorite online yarn stores! Full disclosure: I am an affiliate, but only because I like them so much! I always check them first when I am looking to order new yarn or supplies.

Every time that I have ordered from them, they have always been efficient and I have never had any issues. The Woolery is always quick to answer questions and I love that they have a chat feature (they ask that you please weave a message) on their website to talk to someone even quicker!

They have a fantastic selection of yarns in many different colors that are categorized by yarn type making it easy to find what you are looking for. You can search through pages of cellulose, protein, synthetic, and other weaving yarns. Make sure to look at the info they offer on the yarns they sell. You can find useful stats including ypp, recommended warp sett, and more!

They also offer a wide range of looms (floor, rigid heddle, and frame) as well as weaving tools, and other fiber art tools. The majority of their equipment is new, but sometimes you can navigate to their used equipment page to find some deals!

The Woolery has also recently debuted a new area on their website devoted to earth friendly products so that you can find sustainable materials and even fair trade baskets all in one place!

If you also like to dabble (or get full into) other fiber arts then make sure to check out their different categories devoted knitting/crochet, felting, spinning, dyeing, and more.

Yarn Barn


930 Massachusetts St, Lawrence, KS 66044

Yarn Barn of Kansas is my second go to yarn store. They are probably one of the first that I ever ordered from and I have never had any issues with them.

Shipping is quick and I appreciate their great customer service as well as how easy their website is to maneuver. They include a lot of great information about all their yarns in case you have any questions about their use. One thing that Yarn Barn does that I really like is they often include potential uses for each yarn (great for towels etc.) This can help you to determine if it will drape well or if it will hold up to heavy use.

Yarn Barn separates their yarn first by type of Fiber Art and then by type of fiber. You know you are viewing only weaving yarns when you go through that category on their site. *Note that just because it is a weaving yarn, that does not mean it is necessarily suitable for warp.

Knitters, crocheters, dyers, and spinners – do not worry! Yarn Barn has stuff for you too!

There have been 2 times that I ordered something from them that would take a few days longer to come than expected – and they actually called me to let me know and give me the chance to change my order if needed.

Great customer service!

75 Service Center Rd, Northampton, MA 01060

I have neither visited or ordered from Webs before, but they are one of the larger online options.

Webs has a very large selection of different weaving yarns (and other fiber tools), but some of their yarns tend to be just a little more expensive than the other stores.

That being said, they may have something that the others do not – so they are definitely worth a look!  Just like Yarn Barn they are organized by type of fiber art and they include a lot of useful information such as recommended warp sett and type of project.

I have heard good things about Webs, so I would love to know your experience with them!

Earth Guild


33 Haywood St, Asheville, NC 28801

I have never purchased from Earth Guild online, but I have purchased some cotton from them in store.

They are located about an hour from Penland School of Craft if you decide to make a day trip when you are there for a workshop. The staff was knowledgeable and they have a lot of products to choose from.

Their website is not as user friendly as The Woolery or Yarn barn due to the way they have it organized. They also have less to choose from when it comes to yarn, but they do carry Dragon Tale cotton yarn which I am quite fond of.

While their website design is not ideal, you may still want to give them a chance if you are looking for something specific.

Some other options for buying yarn online that are worth checking out:

Etsy (order handspun and hand-dyed yarns from independent artists!)



Paradise Fibers

Gist Yarn

Dick Blick (I have ordered a lot of stuff from them – just never yarn. Find yarn under the Craft section)

Your Guide To Decoding Weaving Yarn Sizes

Your Guide To Decoding Weaving Yarn Sizes

Let’s imagine a scenario. You are planning a project and you need to buy new yarn (yay!) As you start browsing through your favorite yarn website – you see a lot of different yarns that look like they could be great for your project. Great except that yarn sizes range from 40/2 to 8/4.


Looking at the weaving yarn sizes can feel like you are reading a secret code. What do those numbers actually mean?

Before we move on it is important to note that sizing can vary between different types of yarn. 8/4 cotton and 8/4 linen won’t actually be the same size.

That would make too much sense.

yarn size

First Number

The short of it is that the first number in your fraction is the gauge of the yarn. Just like wire – the larger the number = the thinner the yarn. This is the same no matter the material make up of the yarn (cotton, linen, wool, etc.)

If you’re like me, though, then you might have some questions.

For example: where does that number come from? It all has to do with how many yards per pound (ypp) your yarn is. (We’ll calculate ypp later)

The standards for yarn sizes were decided a long time ago when yarn was first being produced. Cotton, for example, is based off of a size 1 yarn being 840 ypp¹. This gives you an approximate amount of yardage you can expect on your cone or tube. This number is really helpful when planning your weaving.

In contrast to cotton – linen size 1 is 300 ypp¹. This is why an 8/4 cotton and 8/4 linen aren’t actually the same size. 8/4 linen actually ends up being a thicker yarn. Keep this in mind if you are using cotton for samples and linen for your final product.

Unfortunately, there is no direct translation. If you want to figure out similar yarn sizes in a different material than look at the ypp and find one that is equal or close to the yarn you are looking to replace. This information can usually be found where you purchased your yarn – especially if you purchased it online.

yarn size

Second Number

The second number of your yarn size fraction is simply the number of plies your yarn has. 

When fiber is first spun it is called a single. Singles are rarely used in weaving because they aren’t as strong and they tend to have a lot of “energy”. This means they don’t always behave the way you want them to. Sometimes they don’t compress as well or weave as straight. That doesn’t mean you can’t do it – but it will be harder. 

A plied yarn has 2 or more single yarns twisted together. Generally speaking more plies = greater strength. This is why these yarns are more likely to be used for high traffic weavings like rugs.

Most yarns sold for weaving have 2 or 4 plies, but you can sometimes find thicker yarns with more.

This all means that, for example, 8/2 cotton has 2 sets of size 8 yarn twisted together. Likewise 8/4 cotton has 4 sets of size 8 yarn twisted together.

And so on.

It’s also good to note that this sizing isn’t standard worldwide. If you are purchasing yarn from another country then keep in mind that in some countries the size and number of plies might be reversed.

In this case, 2/8 cotton purchased internationally might just be the same as 8/2 cotton purchased in the U.S.

yarn size

Calculating YPP

You can now take these numbers and do a little bit of math.

I’m sorry.

Let’s take 8/2 cotton for example:

First, you will want to take the ypp numbers for a single (840 ypp) and multiply it by the first number of your yarn size.

This would mean that size 8 cotton can be described as having approximately 6,720 yards per pound.

You’re not done yet though.

There’s a second half to that equation. You have to divide it by the number of plies.

The entire equation looks like this:

840 x 8 = 6,720

6,720/2 = 3,360

8/2 cotton has 3,360 ypp.


Let’s put that into action.

Say you have a standard 8/4 cotton with a ypp of 1,680 (840×8/4). If you are looking for a similar sized linen for your project then you would want an 8/2 linen or 1200 ypp (300×8/2). While they aren’t exactly the same, they should be close enough to weave up the similarly. That being said, samples are always your friend.

Why is this important?

Ok, so I’m going to be super honest with you right now. The math we just did? Yeah, that might not be super important to know when you are planning your project. I didn’t know that a pound of cotton size 1 is equal to 840 yards for years into my weaving career and I never had any big issues.

It’s cool to know though for us yarn nerds.

Luckily for all of us, when ordering online most yarn stores tell you the recommended sett range for that warp and the approximate yardage per cone/ tube/ skein. The yardage plays a role when planning the project so you know that you are purchasing the right amount of yarn for your specific project.

That being said – if that information isn’t provided or you can’t find it then you now have the equations to figure it out yourself!

A note on recommended sett: keep in mind that the recommended range is usually for a balanced plain weave so you might have to adjust accordingly. This is where samples once again become an incredibly important part of your studio practice.

So I guess the moral of today’s post is to always read the yarn description and that there is a lot more to know about yarn and yarn sizes than you probably ever imagined.

Yarn Notebook – Organize Your Yarn Stash

Yarn Notebook – Organize Your Yarn Stash

One of the greatest lessons I have learned from having my own studio practice is that good organization can save you.

Now that might seem a bit dramatic – but really it is one of those things that I figured out the hard way.

Even if organization doesn’t come naturally to you (guilty) sometimes you just need to buckle down so you can get through it, because in the long run you will be thankful you did.

In case the title didn’t tip you off: today we’re talking about using a yarn notebook.

It may not be the most exciting part of your studio practice, but it might just be the most helpful.

If I didn’t force myself to keep track of my yarn – I’d run out of something and have no idea what size it was or where to buy more. This obviously could be detrimental if you are mid-project. It can also be a good way to keep your studio stocked with the yarn you use the most. The notebook is an easy and inexpensive way to get your studio together. Pretty much everything you need can be purchased in the office supply section of any store.

The Binder

I’m sure there are many different options for keeping track of your yarn, but I find the most effective way to be in a 3 – ring binder.

I began using these binders for art handouts and notes throughout my time at VCU. They were actually required for the class – but I found them so helpful in the long run that I required them of my students as well while I taught there.

These binders still to this day are a great resource for a lot of my fiber related information and notes. You could even use yours to hold other information beyond your yarn stash. Think about storing samples and their respective information or receipts from yarn and tool purchases in case you can deduct them come tax time. Really you can use this to keep track of anything pertinent to your own studio.

So here’s how I’ve set mine up:

Card stock is a really great option to use for your notebook because it’s heavy enough to hold up to all your yarn samples but thin enough not to be bulky.

I have set up each page as a different type of fiber – but you could divide your pages between retailer, warp sett, or size. Then each each fiber page is split up into the five categories that are most important to me, but you should do what makes the most sense to you.

Possible Categories To Include:



Price per lbs/ cone/ tube



Warp Sett



Number of Cones You Have On Hand

Other Considerations

If you dye your own yarn then it is really important to take good notes. This will help to avoid inconsistencies between dye lots. It’s always a good idea to dye all the yarn you need for each project at one time, but sometimes you need to recreate it. I don’t know about you, but my memory isn’t that good.

You might even want a separate notebook dedicated to this if you dye a lot of yarn.

Think of your dye notebook as a not so tasty recipe book.

Your notebook could also really help you out if you plan on selling your work. Having a well organized account of how much you paid for your materials can be a lifesaver when pricing out a piece that is already made or one that is being commissioned. On that note, a kitchen scale can really help you out to weigh your cones before and after the piece is finished. Doing this helps to get a more accurate account of how much yarn you used and therefore how much to charge for materials.

Don’t let the set up deter you. Setting up your yarn notebook shouldn’t take too much time unless you have a ton of yarn. If that’s the case, I recommend the notebook even more to help keep you straight. Honestly, the hardest part is just remembering to update the notebook when you buy new yarn.
