Crafter Jessica Rice is launching Hat Attack 2 with registration starting Sunday, July 20th. The competition is sponsored by Southwest Trading Company, producers of earth-friendly, “unexpected” fibers and yarns. The last assassin standing will be awarded US$500 worth of SWTC yarn!
From the site:

HAT ATTACK! is a friendly kill or be killed competition where the weapon of choice is a hat. You will receive a target and original weapon pattern. Your goal is to knit and mail a hat to your target before you are killed before receiving one yourself!
