I guess I wouldn't want to be wearing one of these very hats, because they're made to fit a noggin more the size of a 1 or 2 year old. They are each made with a more modern peice of heavy weight cotton on the outside, paired with a vintage peice for the liner. Look for these in my etsy shop.
I'm also taking suggestions on wether or not you think older children, or perhaps adults, would wear a sunhat like this?
