The first blanket I made for the twins was a simple crochet granny square blanket from beautiful variegated blue wool and matching white wool. When I first started making it I didn't know whether I was making it for a boy or a girl and thought that this would be great for either. I edged this with my preferred double-v edging stitch. I'm going to estimate (conservatively) that this blanket took somewhere between 18 and 24 hours to put together. I'm still not a fast crocheter but I do enjoy it and I love the results.
