This is from Melanie Falick's "Weekend Knitting." Originally I was going to knit it with Manos del Uruguay. But the special cast-on was very very difficult to manage. So, I switched to some leftover Plymouth Encore Worsted. It's really a fast knit. I think you can definitely finish it in one weekend. The instruction for decreasing is quite confusing though. If you ever want to knit it and have trouble, let me know. This hat is very stretchy!
