Tannera: Leather Pattern Maker

Tannera turns measurements into leather patterns. Choose a template, enter the size of the card, banknote or wrist, and the pieces and stitch holes are calculated for you. Joined edges get the same number of holes, so the stitching lines up. Save the pattern as a true-size PDF to print, or as SVG and DXF for a laser or cutting machine. Everything stays on your device: it works without an internet connection, with no account and no ads. TEMPLATES • Card holder (1–4 pockets), bifold wallet, long wallet, passport cover, key fob, pen case, watch strap and belt • Object size (card, banknote, passport, pen, wrist, waist), number and step of pockets • Leather thickness for pocket and fold allowance, stitch margin, corner radius • Chisel spacing (2.7, 3, 3.38, 3.85, 4 mm) and hole diameter STITCH HOLES THAT MATCH • Holes start at the corners and are spread at an even spacing close to your chisel • Pockets, linings and tabs take their holes from the piece below: joined edges have the same number of holes, and the count is shown • Folded pieces are checked on both sides • Thread length estimate for saddle stitching EDITING • Drag pieces to move them, resize them with handles or type the measurement • Notches, slots, snaps, rivets and hole marks, fold lines, grain direction • Quantity and mirrored cutting; undo and redo • Millimetres, with inches if you prefer TRUE-SIZE OUTPUT • Vector PDF at 100% scale with 10 mm and 1 inch verification squares: measure them with a ruler after printing • Tiling onto A4 or Letter pages with overlap strips, alignment crosses, page names and a page map • SVG and DXF in millimetres for laser and cutting machines: cut lines red, fold lines blue • Share the PDF, the SVG or the pattern file; print the PDF from the share sheet LIBRARY AND FILES • All your patterns in one library; four sample patterns on first launch and "Add samples again" • Save and share a pattern or the whole library as a .tannera file and open it on another device • Back up and restore Available in 11 languages, in dark and light themes, on phone, tablet and computer.
