I couldn't resist Shelley's new pattern, Variations on a Theme (pdf link). I didn't have a worsted that I wanted to use, so I pulled out a skein of Eco Wool. This is a DK 100% wool yarn. Because of the thinner yarn I cast on 10 stitches more. The resulting hat is a perfect fit (although it won't be for me).
Great pattern - I think the headband is up next!
