The author says it is a rectangle. I am thinking of chaining 23 (the first three should be the 1st st) and crochet til my desired length. The stitch looks like dc. The yarn looks like wool ease thick and quick. So I am going to give it a try. AC Moore is having a sale tomorrow with a 50% off coupon so if Wool ease thick and Quick is not on sale I can have it for $3! Oh yeah size N hook.
