Built for the bench

StitchSpec helps leather workers plan stitch spacing, thread length, and piece setups without replacing your craft — it keeps the math handy while you cut, punch, and sew.

What you can do

Five workshop areas — lab, bench, patterns, pieces, and guide — share the same numbers so a run sheet matches what you actually stitch.

Stitch lab

Dial edge length, stitches per inch, passes, and seam style to see hole count and thread length update as you plan a wallet, belt, or bag panel.

Bench setup

Save leather presets with thickness and waste allowance so every repeat job on the bench starts from the same numbers you trusted last time.

Pattern deck

Stack pattern cards with spacing notes and link them to piece galleries so cutting and stitching stay aligned from layout to final stitch-down.

From guesswork to a run sheet

Compare rough notes with a structured plan before you commit holes to hide.
