Design process

From sketch to pattern: how I design a leather piece

Digital sketch of a bi-fold wallet with a bills pocket, three card slots, an ID and licence pocket and a coin pocket with a snap, drawn in two colour options: blue and brown.

Every pattern in the shop starts long before the first cut in the leather. Here are the steps I go through, from the first idea to the PDF you print at home. Knowing them will also help you when you start designing your own pieces.

The concept

It all starts with a need: what the piece must hold, how it will be used every day, which size it must fit. I write this list first, then I draw.

Sketch page for a cognac wallet. Notes list two bank cards with direct access, ID and other cards with indirect access, bills and tickets, and a coin pocket for four to five coins. Several views show the open wallet, its card slots and a coin pouch with a snap flap.

A concept page: the requirements on the left, then several views of the same wallet.

I usually draw on an iPad, which lets me try several proposals quickly: different pocket layouts, colour combinations, closures. The sketch at the top of this page compares two colour options for the same wallet.

The pattern

Once the design is settled, I move on to the pattern itself. This is where every measurement matters: the size of each piece, the stitching allowance, the order of assembly. The goal is a piece that is both strong and practical to use every day.

Printed pattern sheets for the French Identity Card Holder with 7 pockets. Each leather piece is outlined and labelled, such as Base, Pocket L1 or Pocket R2 with the number of copies to cut. A header lists recommendations: leather thickness 1 to 1.4 mm, stitching line at 2 to 3 mm, hole punch spacing 3 to 4 mm.

Each piece is labelled with its name and the number of copies to cut, and the sheet lists the leather thickness, stitching line and hole spacing I recommend. A small test square lets you check that the pattern printed at true size.

The prototype

When a design is unusual, I first build a prototype in a cheaper material to test the shapes and the techniques before using good leather.

Two purses side by side on a cutting mat. On the left, a rough prototype in pink and turquoise material with visible hand stitches. On the right, the finished purse in brown and blue leather, open, showing inner loops and neat saddle stitching.

A prototype also checks the measurements against the real objects the piece must hold. For this purse, I even 3D printed a box with the same dimensions as the item it had to contain.

Making the piece

Then comes the actual making: cutting, preparing the pieces, finishing the edges and stitching everything together. Depending on the complexity, it takes between 1 and 12 hours. Many of these steps are filmed on my YouTube channel.

From my workbench to yours

When I publish a pattern, you get the result of all these steps: a tested design, printable templates, step-by-step instructions and, for many patterns, a making-of video. You can browse them by type of project below.
