I used this pattern on Raverly.com. Instead of an icord cast on, I tried my hand at a provisional cast on. I also switched it from being fully lined to only lined around his ears like a ear muff or headband (similar to this hat pattern).
He was so excited he didn't want to take it off, even though it was a warm summer evening. His dad finally convinced him to take it off because I wanted a picture of the inside of his new hat.
So happy when projects work and make my kids smile!
