This isn't strictly a masterclass wallet, but does use a bunch of skills and details I've pieced together from other masterclass slot card holders and the newer bifold wallet project. I made this out of 0.4-0.6mm Buttero belly, lined everything with 0.2mm reinforcement, and stitched with Fil au Chinois. The front pocket edges are turned and the outer edges are burnished. There's a third pocket opening on the side. I'm imagining there is some way to get all the outer edges turned like the bifold but it will likely require considerably more skiving practice.
Nice work! A clean practical wallet, I like it. Great shots too.
Great looking wallet! How is the clip attached?
