I don't *need* any more patterns. I have a couple of lifetime's worth. Doesn't mean I don't want them though. I've been thinking about getting this one because I've never crocheted mittens. I'm sure I could figure it out, but sometimes I don't want to. I like when other people do the math. :-)
It's from Interweave and is billed as a simple recipe that will teach you how to customize and crochet your own mittens. Click the mitten for the link.
