I'm sure that I will feel silly if someone can explain this to me, but I can't seem to find an answer/ figure this out for myself:
I've knitted most of a log cabin blanket -- and I have a big square. I want to knit an edging for it so that one color of stitches goes all the way around the blanket, if you get my meaning. I don't want it fancy or anything -- just garter stitch. Will I just pick up stitches all the way around? Mostly, I don't know how I can deal with the corners. Clearly, I need to increase, but I don't know how much, or how many, or what increase is best.
Any help is very much appreciated.
