These also make nice little accessory pouches since they close up. People use them to carry thumb drives, bike parts, lady products and, of course, change.
I've been working on some designs that have a bill pocket, since that's what people want, I guess. Tried some designs with leather but fell back to a design I made a few years ago. I'd never been that pleased with it since the extra layer bulked up the seams too much, but I've been working with difference combinations of lighter fabric and I'm liking it better.
This one's 500d Cordura nylon.
The bill pocket wraps around the front to make another card pocket. Pretty cool.
