I took the hat on my trip and it was used a lot. Worked perfectly in my opinion. On one windy day it occurred to me it might be good to add a cord or strap to keep it on. I think I will do that for my rainhat version.
I spent a couple of hours drafting the pattern and turning it into a .pdf file this afternoon. (See how much I love my big-headed friends?) If you want a copy of the pattern leave a comment with your email address in it and I will send it to you.
I found some great fabrics today for rain hats, which I will make from the same pattern. I found a store that carries all kinds of outdoor type fabrics, as well as all the clips and toggles and zippers and other goodies one might need. For those of you in Portland, you need to check it out! For the rest of you, they do mail order, but you miss out on the bin of remnants where I found my fabrics. Rose City Textiles. This was a great resource and the clerk I worked with was super helpful and knowledgeable.
