Just finished a totally reversible Buffalo Check Hat & Cowl. It was a real learning experience. No instructions, I made both up! 1 skein of red and 1 skein of black Cascade 220 yarn for both. The yarn is between fingering and worsted weight. 72 (144) sts for the hat; 90 (180) sts for the cowl. It's double knitted; knitting both sides at the same time.
