What kind of hat do you want? You can probably make it with wool, without knitting, just felting. Felting is an ancient technique of making material, predating spinning and weaving, from slippers found in East Asia 2,700 years ago to yurts in Mongolia to hats and mittens in Scandinavia. Simply combining wool fibers with water and soap and adding patient agitation, (this is not a washing machine project!) you will shrink and sculpt your wool into a desired form to fit your head. You decide whether it is a camo hunters cap, a beret, a toque, a rolled brimmed hat, a hat for winter or a hat for fashion.
