I think smocking might be my next detail-thing-that-I'm-really-into. Time will tell ;-) In the meantime, this hat is a great introduction to afterthought smocking, a very simple technique that livens up simple ribbing with just a few passes of the needle. It's made with Madelinetosh Tosh Dk in "Cosmos" which is a simply magical colorway- I could swear it changes from purple to green depending on the light.
