I love your work...new logo and all
If I may suggest, you should try and make a few "Magic Wallets"
They are basically two leather (or whatever material) sides with crossed elastic joining them. This makes it so that any $ or cards placed inside will be held down by the elastic tension. They make duct tape versions here on you tube

I am a hobby guy so do this all for fun and relaxation. Would like to see somebody who knows what they are doing make them.
Cheers, Scott
