You make a garment and need to make buttonholes, we all know the simple one knit 2 together and yarn over and then pick up the yarn over on the way back for a small button. Or we cast off and then cast on on the way back. But they never quite look right. Well these buttonholes are beautiful and next time I need some I am going to try this method. Looks like it will take a few minutes but you don't want a beautiful cabled sweater with crappy looking buttonholes.
