I love this stitch - there is no front or back, only your favorite. The final crochet edge is a beautiful finishing detail and looks great on either side. The directions for an afghan size are also included. Numbers within the pattern are given as follows: outer blanket (worsted cotton blanket, outer afghan, worsted cotton afghan).
outer blanket & afghan: 12 sts & 12 rows = 4" in slip stitch pattern. Worsted cotton blanket & afghan: 22 1/2 sts & 21 1/2 rows = 4" in slip stitch pattern.
Because this is a blanket, gauge is not critical. If you are a tight knitter or want more loft, you may want to go up a needle size to get a beautiful drape. Go for the fluff factor!
