I've made a slightly larger sacoche bag using Tsugaru Kogin-sashi embroidery. The length of the strap is adjustable, so it can also be used as a waist pouch. There's a zippered pocket on the back. My favorite long wallet fits perfectly sideways. How about using it for shopping or walks, carrying your smartphone, wallet, eco-bag, etc.?
