:INFO Choosing the Right Leather Weight Vegetable-tanned leather is the standard for hand-stitched wallets because it holds shape over time and develops a patina with use. For a slim card wallet, use 2 to 3 oz leather (0.8 to 1.2 mm thick) for the card pockets and 3 to 4 oz (1.2 to 1.6 mm) for the outer shell. Chrome-tanned leather is softer and more pliable but does not tool or burnish as cleanly. Buy vegetable-tanned sides or shoulders from a tannery or craft supplier rather than craft store scraps, which are often corrected grain with a plastic coating that does not age well. :PATH Cut Your Panels Use a metal ruler and rotary cutter or sharp utility knife on a cutting mat. | :INFO Cut Your Panels Use a metal ruler and rotary cutter or sharp utility knife on a cutting mat.

That is what makes it worth doing by hand. :NOTE Tools Worth Buying Once A good pricking iron and a sharp swivel knife are the two tools that separate clean work from frustrating work. Cheap pricking irons bend or space unevenly and make every stitch line look crooked. Spend more once on quality tools and the leather cost becomes the small part of the equation.
