About a year and half ago, I made Bruno a duct tape wallet to replace an earlier one, which I’d also made. It’s in this earlier post, with a few pictures of the process. His has worn out, I made two more. I sent him the purple wallet, and the blue wallet in the earlier post. I’m keeping the black one so that I have an example on hand. When I make one every year and a half or so, a working sample is good!
