A Yarn Over (YO) is created before a knit stitch by just bring the working yarn to the front of the fabric. As the next stich is knit, the yarn curls around the needle and forms an additional slanted looking stitch.Brand new knitters frequently forget that the yarn has to be behind the knitting before a new stitch is knit. This is usually a result of putting the knitting down mid row and the yarn is accidently brought to the front.
This picture shows the yarn over under the arrow as it would appear when it has just been knit. The slanted wrap really belongs under the needle rather than on top of the needle.
If it is near the end of the row unravel a few stitches and just drop the yarn over off the needle. Note that the sample is now eleven stitches wide. Also there is no purl bar under the yarn over stitch.
More often, that yarn over is found on the return row. The slanted stitch of that yarn over is clearly visible when seen from the backside.
So you found the hole on the next row and do not want it! It is still an easy fix. Knit up to the yarn over as shown to the right. Drop the stitch from the needle. (Dropped stitch loop is on a stitch holder so that we can see its progress.).Should you find the yarn over several rows later, you can still drop that stitcch. It will only run down to the original yarn over and stop there. Because knits are so stretchy, the excess yarn will just get absorbed by the adjacent stitches and not be seen. Keep in mind that this only works for a max of three rows. After that, a line will form showing excess thread from the dropped stitches.
If you knit into the yarn over, it becomes a stitch. It is the beginning of lace, buttonhole, or an eyelet. The top of the sample to the right shows the hole created by working into the yarn over. The stitch holder shows that first loop of the dropped stitch as it disappears into the fabric.
