This is the fair isle hat from knittingpatterncentral.com. I used DK weight yarn and size 4 circ needle to do this, otherwise followed the pattern, and it turned out to fit my head which measures about 22 inches. It was a little tight before blocking, now perfect. I don't know how it would fit anyone if knitted with worsted weight and size 6 needles as described! This is my first attempt to post a pic, hope it works! I am really happy with how this turned out. Learning to do fair isle style knitting was really fun!
