I knit this hat in a hand painted wool and alpaca blend yarn. I worked one by one ribbing through the entire body of the hat. To prevent flaring at the cast on edge, I worked two rounds of slip stitch edging. To add interest and break up the ribbing, I worked two garter stitch ridges about 3 ½ inches up the body of the hat. The top is decreased while maintaining the ribbing so that it remains stretchy like the rest of the hat. The gray colors of the hat are nice, but the guard hairs show up quite a bit in this yarn, making it itchier than some people might like for a hat that sits against the skin.
