What are you most proud of? I love the fit - Nels' head is 21" and the hat fits this size perfectly with a little room to grow. What advice would you give someone starting this project? Be careful hat-sewing... the slightest deviation can result in a too-small or too-large result. When looking for a pattern, see if you can find one with elastic play in the hatband, if you don't mind the small style-sacrifice.
