What are you most proud of? Having completed the entire process so the hat is wearable. The original pattern is a little vague on shaping and having overcome those challenges, I feel accomplished. What advice would you give someone starting this project? Know how to make boiled starch. Choose your materials and needles with care - a tighter mesh holds starch better and provides more surface onto which the starch can adhere. Either have a hat block or make a "water proof" one. Consider how you will be making a hat band (sweat band) -- and how you will apply it. This band provides the major stability for the hat and prevents the crown from "stretching" with use.
