I found this cap in The Knitter's Bible: Knitted Accessories and it looked so comfy I had to try it! I'm knitting it out of cascade yarns (Quatro; peruvian wool) and it's coming out beautifully! Using size 5 and 7 needles and it knits up rather quickly.
Here is a pic I found of it on the net. I will post pic of my FO when I'm done!
