This is my first bag trial run to work out the kinks. Veg tan and reusing found leather from a pair of chaps. Lots of unused punched holes and probably the worst stitching in the history of mankind, but I feel good about doing a bag now. I used the laser cut pattern to be sure about the main holes for stitching. Additional holes are for testing other design elements.

Back panel cut out for branding and strap alternative.
I used the original strap connectors to add snaps for holding usb sticks on a key ring
Two closing tabs. Top one closes more securely
Added studs to bottom and the other things are snaps that secure the lining
Side snap for adding keys or simple bag tie down
