I've always liked this little cap design which I saw first in the book, Knitting for Peace. Now, the pattern is a freebie on Ravelry. You can find it here: http://www.ravelry.com/patterns/library/swirled-ski-cap
It's an interesting approach to knitting what is essentially a toque. This one's in 100% wool, worsted weight. It knits up quickly.
