Swatching in the Round (Speed Swatch)
Most knitters knit slightly looser in the round than flat. For socks, hats, and seamless sweaters, a flat swatch is misleading — but knitting a small tube as a swatch is wasteful. The "speed swatch" simulates round knitting on a flat needle by leaving long floats across the back of the work.

Method
Cast on roughly 30 stitches with a circular needle. Knit one row. Without turning, slide all the stitches back to the right end of the cable, bring the working yarn behind the work loosely (a 5–6 inch float), and knit the next row. Repeat for at least 30 rows. Cut yarn, weave in ends loosely (or leave the floats), and block.
What it looks like
On the front: every row is a knit row, just like the round-knit fabric. On the back: long horizontal floats at the end of every row. The fabric measures and behaves like a round-knit fabric.

Tips
- Block the speed swatch as a square panel, not as a tube — the floats will pull in slightly and you'll measure honest round-knit gauge.
- Use the long tail and the float ends as a built-in note: tag your swatch with needle size and yarn on the float.
