Pictures are illustrations: computer drawings of each model. Yes, as a helper. Every pattern piece starts as my own drawing in Inkscape, and the sizes come from my own formulas. An AI assistant helps me assemble the patterns in all their variants (iron spacings, paper sizes, opening styles) and lay out the instructions — always following my instructions. I check every result and correct it, often by hand in Inkscape. Nothing goes on sale before I've checked it. All pictures on the site are illustrations for now; photos of real leather builds will follow, marked “Photo”.
