Finally I found a usage for this wonderful, very small piece of fabric from my mothers collection of "odd and tiny pieces from the 70's." Very simple construction - you can kind of see exactly how it's made. (If not, ask me.) I covered the backside of the fabric with transparent duct tape (Silvertejp) before I sewed to make the wallet more durable. Let's see how well it works out. I'll start using it tomorrow.
