I'm working on my first project in the round, a hat for DH. The pattern is Here. The pattern says to continue the K2P2 rib until you have 9.5 inches. I don't want to fold the brim of the hat up, he wants more like a beanie. My question is, when should I start my decreases? From the pictures, it looks like there are about 2 inches of the brim folded up. So should I start my decreases between 7 and 7.5 inches? Any advice is more than welcome. Thanks!
