A yarn over is the easiest increase in knitting. You wrap the yarn once around the right needle, and that wrap becomes a new stitch on the next row. It also leaves a small hole, which is the whole point in lace. Rokolee of Rokolee DIY shows it four ways, because the move changes a little depending on the stitches on either side. She also covers the next row, and how to undo a yarn over you made by accident.
How to knit a yarn over: the one rule
Every yarn over is the same motion. The yarn wraps once around the right needle, counterclockwise, coming over the top from front to back. What changes is where the yarn starts and where it has to end up. Before a knit stitch it must finish at the back. Before a purl stitch it must finish at the front. Keep that in mind and you never need to memorize four versions.
Reading yo in a pattern
| Pattern says | What you do | UK name |
|---|
| k1, yo, k1 | Bring the yarn forward between the needles, then knit | yfwd |
| k1, yo, p1 | Yarn forward, wrap over the needle, forward again, then purl | yrn |
| p1, yo, p1 | Yarn over the needle to the back, forward again, then purl | yrn |
| p1, yo, k1 | Leave the yarn in front and knit | yon |
Why a yarn over makes a hole
The wrap is not pulled through any stitch below it. It floats on the needle with nothing anchoring it, so when you work it on the next row it leaves an open eyelet. One yarn over adds one stitch. Lace patterns usually pair each yarn over with a decrease such as knit two together, so the count stays the same and only the holes are left. If your stitch count keeps creeping up, check that every decrease is there.
Choosing yarn for yarn overs
Rokolee practices in chunky yarn so the camera can see every wrap. Holes in chunky yarn look big and a bit clumsy. For a real project, pick something finer. Fingering, sport or DK weight shows off eyelets best, and a smooth, light color makes the pattern easy to read. Fuzzy mohair and dark shades hide the holes.
Common mistakes
- Accidental yarn overs. The yarn is left in front when you start a knit stitch, often right after a purl. Count stitches at the end of each row.
- Wrapping the wrong way. A clockwise wrap twists the new stitch and the hole closes up. Always go over the top, front to back.
- Losing the loop on the next row. A yarn over is loose and slides off easily. Treat it as a stitch and work it.
- Forgetting the matching decrease. The holes appear but the piece slowly gets wider.
