GPW, my uncle used to wear one of those hats. His first one had beer logos from a certain St. Louis brewery on it. He wore it untul Grandma couldn't stand how bad it looked. She deconstructed what was left and made him a new one out of some denim she had laying around ( she made rugs so there was lots laying around). Then everyone in the family soon ended up with denim hats. I know he went through several over the years. He may even have one or two left. Grandma always made sure they disappeared if the holes got too large. But there was always a replacement.
