I knit this hat in wool tapestry yarn I found at the thrift store. The yarn worsted weight yarn more suitable for outerwear than next to the skin, but that will make the hat quite sturdy and warm. I used the last bits of several skeins left over from other projects to add pops of color and stripes to this hat. Just a few rounds of color work here and there really make the pattern pop, and nothing is more than a repeat of four stitches around. The top of the hat incorporates a tiny bit every curlicue yarn as I ran out of wool yarn for the top. As usual a decreased for the top quickly over just a few rounds to finish off the hat.
