Buttonholes
From KnitWiki
When knitting, buttonholes can be created in the knitted fabric in several ways. Most methods are performed as you come to the desired location while working the piece, but others can be performed after having worked the piece to completion.
Any type of knitted buttonhole can be strengthened and given neater edges with embroidery, particularly the blanket stitch or whip stitch.
