It's been awhile since I've knit a buttonhole, so I needed a refresher's course. There are lots of ways to make them, for all sorts of purposes, and if you are following a pattern, it will tell you which is needed. I'm making a teething bib for a shower, inspired by a beautiful set of bibs a friend sent me when Evie was born. I'm using a yarn-over button hole. It's super simple, so even if you are teaching yourself to knit (like myself), it's super easy. Once you reach the place in your row where you need a buttonhole, knit two together. If you are following a pattern, it's probably abbreviated "k2tog."
|Knit 2 stitches together|
To yarn over, all you have to do is move the string from the back of your work to the front.
Then, continue knitting to the end of the row. When you turn your work, knit all the stitches.
And that's it! Another job well done.
