I made a simple hat to go with the mulberry scarf I finished the other day. I just made up a pattern. I started with 12 dc in the 1st round, and made 6 increasing rounds, then continued the non-increasing rounds until I ran out of yarn. You normally put 7 increasing rounds, but this yarn is quite thick so it was bigger. I used a 4mm hook.
this is a simple hat that goes with a matching scarf
