I made this in 2005 or 2006 but haven’t used it in a while. I found it in the cupboard today and decided it needed to be resurrected!
I based this VERY loosely on the Kureyon Kozy pattern from Knitty. I used the beginning pattern for the double layer base but just knitted it to the correct diameter and then knit up in the round. I used the jogless jog technique for the stripes. A few rounds of 2x2 ribbing and voila!
