If you're thinking of knitting or crocheting a blanket, you need some blanket yarn! But what to buy? There are lots of different options in a wide range of styles and weights, so whatever your need there's a perfect yarn out there for your project.


One of the first things to think about when choosing a blanket yarn is weight. Do you want a lighter-weight blanket for summer evenings, or something super-cosy for winter? Take a look at our yarn weight conversion chart for a guide to the different yarn weights available.

The next thing to consider is the fibre. While you might want to splash out on a natural fibre blend, remember that baby knits and blankets that will frequently be used by the whole family (including pets!) ideally need to be easy to care for and machine washable. Wool roving yarns may be beautifully soft, but they can pill easily, so consider keeping them for luxury blankets and using man-made fibres for the everyday ones.

There are some fabulous yarns out there created especially for blankets, so don't limit your search to your go-to yarns for other projects. Look out for self-striping blanket yarns, super-sized ones, cosy chenilles or flannels, and fun and funky textures.

In this guide we'll help you choose a blanket yarn, and also offer advice on how much yarn you might need, what pattern to choose, and how to look after your finished make. Read on for all you need to know about blanket yarn…

How much yarn for a blanket?

When you're making a blanket it's important to think about how much yarn you need before you start – you don't want to run out half way through! If you're following a pattern, simply take a look at the materials and tools section, which will tell you how much of each yarn you need.

What if you don't have a pattern? Well, with a bit of maths you can still figure out roughly how much yarn for a blanket. First you need to know your yarn's tension, which is printed on the ball band. The tension tells you how many stitches and rows will create a piece of fabric 10 x 10cm square, using the needle or hook size and stitch given. If you'll be using the stitch on the ball band, simply check your tension to make sure it matches (see our guides on knitting tension squares and how to perfect your crochet tension to find out how), going up or down a needle/hook size if necessary. When you have a perfect match, make a swatch that measures exactly 10 x 10cm square. Now measure the weight of the yarn you used.

You can then estimate how much yarn you'll need for a whole blanket. Say you want your blanket to be 100cm x 100cm square, you'll need 10 times the amount of yarn you used for your swatch. If your swatch used 30g of yarn, you'll need 300g in total for your blanket.

What if you'll be using a different stitch to the one listed on the ball band? In this case you can use the same technique, but be aware that the stitch pattern will affect the final tension. You may need to use some trial and error, and make a few different swatches using different size needles, to get the result you want. You can then measure the amount of yarn in a 10 x 10cm square and calculate the full amount required as before.

If you plan to make blanket squares rather than working your blanket in one piece, you could instead create a single square, wash and block it (following our guides on how to block knitting projects or how to block your crochet using a blocking board), and use its measurements to calculate how many squares you'll need overall. Make sure you allow extra for the edging and any joining stitches too.

However much yarn you need, we'd generally recommend buying an extra ball just in case. Even if your calculations are spot-on and it isn't required for the blanket, it's always useful to have some spare yarn for sewing up and future repairs.

How to make a yarn blanket?

If you're a knitter, the easiest yarn blanket to make is a garter stitch one – check out our guide on garter stitch for the pattern. For crocheters, we'd suggest a basic granny square design. You could sew together lots of small squares, or just keep adding more rounds to make one giant square! Find out how to make a crochet granny square with our tutorial.

How to wash a yarn blanket?

If you've ever put something in the wash only to have it come out three sizes smaller or a completely different colour, you'll know how important it is to look after your precious creations correctly.

So how to wash a yarn blanket? Well, it depends on the yarn you've used. An alpaca and cashmere blend blanket will need very different care to one that's made from 100% acrylic. To clean your blanket properly you need to follow the washing instructions that are given on the ball band that came with your yarn. If you've thrown it out, have a look on the company's website, as they may be listed there too.

On the ball band you should see washing symbols, which tell you whether the yarn can be machine washed, tumble dried, dry cleaned and hand washed. If you're in any doubt about the fibres your yarn contains, or whether it's suitable for machine washing, we recommend gentle hand washing only – just in case!

When your blanket comes out of the wash it's a good idea to dry it flat so that it doesn't stretch or distort. Big blankets in particular can be very heavy when they're wet! If you have a laundry airer that lies flat over a bath, this is a great option. Or simply place the blanket on some towels on the floor.

To keep your blanket looking its best you may also want to block it. This is the process of smoothing out the finished fabric to reduce curling and make the stitches look more even. Find out how it's done in our guide on how to block knitting projects.
