Craft Begins with a Pattern

Patterns built for the irons you already own.

Every sheet is generated from one cross-checked geometry system. You pick your pricking iron spacing, and the stitch holes land exactly where your tool punches — no fudging the last three holes at the corner.

One pocket, generated for your irons

Horizontal Small Pocket
Choose your pricking iron spacing

25 stitch holes across the bottom edge · panel 108.0 × 55.3 mm

Click through the spacings. The hole count recomputes, the panel height adjusts and the corner geometry follows — nothing is stretched or approximated to fit. Whichever irons are on your bench, you get the sheet that was calculated for them.


Why these and not the other thousand

Six things you can check for yourself before spending anything.

Made for your irons

Choose your pricking iron spacing at checkout — 2.7, 3, 3.38, 3.85, 4 or 5 mm. The holes land where your tool punches.

Prints at true scale

Every sheet carries a scale strip: a 20 mm bar, a 1 inch bar, and a row of holes at your own spacing. Check it before you cut leather.

One system, many models

Panels are designed to combine. Learn one, and the next twenty use the same construction logic.

Free to try, no email

Model No.001 is a gift. No signup form, no drip sequence, no catch. Download it and judge the work yourself.

Corrections are published

Every sheet is version-stamped, and every fix gets listed openly. If something was wrong, you'll know what and when.

Sell what you make

Single-maker licence: build and sell as many finished pieces as you like. The only thing you can't pass on is the pattern file.


How it works

Three steps, and the second one is the part most patterns skip.

STEP 01

Pick your spacing and paper

Tell us which pricking irons you own and whether you print A4 or US Letter. You get the sheet generated for that combination — not a compromise version.

STEP 02

Print and check the strip

Hold a ruler against the 20 mm bar and your iron against the hole row. If both match, your printer is set correctly and the pattern is exact. Thirty seconds, before any leather is cut.

STEP 03

Cut, punch, stitch

Trim allowance and stitch lines are drawn separately, corners are marked, and the written instructions cover assembly order.

Something non-standard? The stitch line inset and trim allowance are adjustable too — they're not on the menu because most makers don't need to think about them. If you do, write to me and I'll generate it.


Is this you?

Four situations these patterns were built to solve.

Your irons aren't 4 mm

Almost every pattern on the market is drawn for one spacing. If you own 3.38 or 3.85 mm irons, the holes drift, and you end up improvising at the corners. Here you pick the spacing and the drift doesn't exist.

You've been burned by a bundle

Two hundred patterns for nine euros, and half of them don't actually assemble. These are generated from one verified geometry system, cross-checked panel by panel, and version-stamped so you can tell which sheet you have.

You're not sure it'll print right

Scale errors are the most expensive mistake in leathercraft, because you find out after cutting. Every sheet here carries a printed scale check you can verify against a ruler and your own iron.

You want to sell what you make

The licence is explicit: unlimited finished pieces, for yourself or for sale, no royalty and no permission needed. Only the pattern file itself stays put.

What's coming

Being straight with you: the store isn't open yet. Model No.001 is real and free today. Here's the order of everything else.

First

Puzzle Horizontal

Sixteen models built from one panel system — card holders, wallets with a cash compartment, passport holder, field notes cover.

Next

The combination map

Which panels assemble into which finished model. The panels are the alphabet; this is the dictionary.

After that

More series

Vertical card holders, then belts and watch straps. Same system, same precision, same spacing choice.

Alongside

Tools and guides

A free pricing calculator for your own finished work, and written guides on tooling and suppliers — kept updated rather than frozen.


Tell me what to build

Six questions, completely anonymous, about ninety seconds. What you answer decides which spacings get made first and which models come next. There's a box at the end for anything you wish existed and can't find — that one matters most.
