It's important to swatch in the round for any knitting project that will be worked in the round, whether you're knitting a sweater, a hat, or a cowl. New to knitting? Swatching is an important part of the process of knitting any project where the finished size matters - you probably want your new sweater to fit you instead of your friend who's 3 sizes smaller! Before learning how to swatch in the round you might want to brush up on the basics of swatching, and why gauge (which is what you're checking when you swatch) matters.
Swatching in the round can be a pain, and it's often inaccurate. Use a simple trick to make swatching in the round easier and more accurate!
It's always a good idea to make a swatch that matches how you'll knit your project, you want it to be an accurate test of how your fabric and gauge will turn out in the project. Knitting in the round adds an extra complication because instead of alternating right side and wrong side rows you're only working right side rows. That means that if you're working stockinette, or any stockinette based stitch pattern, you'll only be knitting and not purling.
There are many ways to knit, but whichever style you work in one thing remains constant: knits and purls are never worked in exactly the same way. Consequently it’s very common for knit and purl stitches to be slightly different sizes. This can cause a range of visible tension inconsistencies and next week’s post will cover dealing with those. It also means that it’s common to find a difference in gauge between stockinette worked flat (with purls) and stockinette worked in the round (no purling).
Beginning with a sleeve is often recommended as a way to avoid swatching for a sweater but it's not a very reliable method. The reason is that sleeves are smallish tubes and you’ll be using magic loop, dpns, or circulars with shortened tips to knit them. You might grip those short needles tighter to avoid them flying everywhere;, pull the yarn tight to avoid ladders at the joins; or just tense up a bit. The odds of your gauge being tighter than it normally would be on that needle size are high. We find that it's very common for our sample knitting team to use a larger needle size on sleeves than than they used for the body of a seamless garment.
Knitting a swatch with a 16″ / 40cm circumference so that the stitches fit around a circular needle, or even one with a 24" / 60cm circumference so that you can use regular length needle tips, is possible. It will probably result in a very accurate swatch and a lovely, large piece of fabric where you can really see how your garment will behave. It's also a lot more knitting than the vast majority of us want to do for a swatch, particularly if you find the gauge is off and you have to make another!
It’s not knitting a tube that matters for swatching in the round. The crucial thing is whether or not you’re working wrong side rows.
All you need is your yarn and a circular needle (preferably the needle you plan to work the project with, or at least one in the same material).
Begin by casting on at least 1 and a half times your desired gauge over 4" / 10cm. Eg. if your desired gauge is 20sts per 4" cast on at least 30 stitches. This method results in several loose stitches at either side, which you won't want to measure.
Knit 1 row, without turning at the end.
Slide all of the stitches to the other end of the needle, just like making an I-cord.
Bring the yarn around the back of the work and knit across with right side facing. At the end of the row slide the stitches along the needle again. Continue in this manner, letting the yarn trail loosely across the back.
If you find it difficult to keep the strands loose just let them tighten up.
You can cut them at the end so that the swatch lies flat. Make sure you have plenty of yarn for your project before cutting the swatch though!
This method is perfect for swatching for stranded colourwork, which most knitters find it easier to work in the round.
