splityarn calls this the "Easiest Knitted Sweater Zipper Install Ever" and it looks like it might be. I haven't tried it yet but I'll let you know if I do - my one attempt to put a zipper into a knitted sweater came out OK, but not this nice.
Free knitting pattern for a super simple, easy to knit seed stitch cowl. It uses one skein of yarn, and can be knitted up in one night! I may have to learn how to do that. (point: not crochet, but I only have one yarn-y board)
