This is a "two for one" hat. It's a long tube (decreased at both ends). You push one end into the other and get a double layer hat. I reversed my striping on the inside so I can wear this hat either side out. The striping sequence is the Fibonnacci Sequence (one of my favorites). Gauge is 6 sts. to 1 inch so you have a warm hat that is not to bulky. (Designed by Anna)
