The video above shows yarn overs made with yarn carried in right hand.
When knitting yarn overs, you are creating another stitch. In other words, you are increasing a stitch. Sometimes, this is used as a decorative increase. Other times, it is used to create an eyelet, in which case it will be preceded or followed by a decrease to keep the stitch count in check.
There are actually different ways to work a yarn over, though. It depends on whether it’s snuggled between 2 knit stitches, 2 purl stitches, or between knits and purls. These directions are specific to those that knit with yarn in the right hand, as in English or American style.
- Knit to knit- move yarn to front as if to purl, let it fall over the needle and move to the back.
- Knit to purl-move yarn to front as if to purl, let it fall over the needle and to the back, then again to the front.
- Purl to purl-move yarn over the needle and back to the front.
- Purl to knit- leave yarn where it is and simply knit the next stitch.
For those of you that hold your yarn in the left hand, as in Continental or German, the main difference is that you are moving your needle as opposed to your yarn.
- Knit to knit- move needle behind the working yarn and move forward.
- Knit to purl- move needle behind the working yarn, in front and behind again.
- Purl to purl-move needle under the yarn from the front, then up and over to the front again.
- Purl to knit- move needle under the yarn from the front.
With that said, you might want to experiment a little. I’ve done some yarn overs that go from knit to purl or purl to knit that require an extra little wrap to avoid getting lost in the fabric. The main thing to remember your yarn over should sit on the needle as a normal stitch would. The right side of the stitch should be on the near side (slanting to the right).
