She cast on another hat--this time in sock weight yarn.
Cherry Tree Hill Supersock in Cherry Chip colorway, on size 4 Harmony needles.
I was kind of surprised at how few patterns for fingering weight adult size hats there are out there. The few I did find, I didn't really like, so guess what? I'm going to make up my own.
The first few rounds will be K2 P2 rib. I'll figure out what comes next when I get there.
