Wow, thank you for the compliment.
Thank you,. I found a how to online. I made my pattern off that onto posterboard. It was to small, so I had to redraw it and keep cutting out the inside of the brim pattern till it fit my head loosely. It still ended up being tight after everything was sewn together. So I had to wet it and stretch it to fit my head. I still hae some work to do on the measuring thing myself. I think it would be hard to make these for someone else by mail order. Relying on someone to measure their own head correctly would be chancy.
