This rattlesnake beanie is a wing-it. (Meaning I got an idea and am making it up as I go.) It's knitted from left over wurm wool and mostly thick Lang West (roughly half wool half acrylic) in browny black. I've gotta weave in some ends and add some details yet but I'm eager to see the finished product. I think it will go down a hoot with my soon-to-be 8 year old nephew!
