In knitting, yarn over means exactly that. You bring the yarn over the needle and then knit whatever knitting stitches are required after that. It adds an extra stitch between stitches and is used to make a hole for a button or create a decorative element. Doing a yarn over may seem a bit awkward at first, but depending how they’re arranged, this knitting stitch is often used to make things larger like the space for a thumb in a mitten.
Regardless, this knitting video will show you how easy it is to do. and if you’ve ever wound up with extra stitches, you probably did this accidentally. Especially if you are switching between knitting and purl stitches.
