Using a stitching punch is straightforward, but taking care with your setup will give you cleaner and more consistent results.

1. Mark your stitching line

First, establish the position of your stitching line using a wing divider, stitching groover or another suitable leathercraft marking tool.

Keep the line a consistent distance from the edge of the leather.

2. Choose the correct punch

Select the punch according to the result you want:

• Choose 1mm or 1.5mm for your desired hole diameter.
• Choose 5mm or 6mm for your stitch spacing.
• Use the 6-prong punch for longer straight sections.
• Use the 1-prong or 2-prong punch around corners, curves and difficult-to-reach areas.

3. Position the punch

Place the points of the punch directly over your marked stitching line.

For the first set of holes, take care to position the punch accurately. This establishes the spacing for the rest of the stitch line.

4. Punch the leather

Place the leather on an appropriate punching board or cutting mat and strike the punch with a suitable leathercraft mallet or maul.

Use controlled, even strikes rather than excessive force.

Make sure the punch is held vertically so that the holes remain consistent through the thickness of the leather.

5. Continue along the stitch line

For straight sections, the 6-prong punch allows you to establish multiple holes efficiently.

When approaching a corner or curve, switch to the 2-prong or 1-prong punch to maintain control over the positioning of each hole.

6. Stitch your leather

Once all the holes have been prepared, thread your chosen leatherworking thread and stitch using your preferred technique, such as saddle stitching.

The round holes provide a clean and consistent path for the thread.

The best configuration depends on your leather, thread and preferred stitch style.

1mm / 5mm: Fine leather goods and smaller projects

1mm / 6mm: Fine stitching with a more open appearance

1.5mm / 5mm: General leathercraft and a more substantial stitch

1.5mm / 6mm: Larger projects and a more pronounced stitch pattern

1-prong: Corners, curves and individual hole placement

2-prong: Curves, corners and controlled positioning

6-prong: Fast punching along straight sections

For maximum versatility, combining a 6-prong punch with a 1-prong or 2-prong punch provides good coverage for both straight sections and detailed areas.

Unlike diamond-shaped pricking irons or stitching chisels, these circular hole punches create round stitching holes.

Round holes can give hand-stitched leather goods a clean and understated appearance and are particularly suited to leatherworkers who prefer a more minimal stitch-hole profile.

The punches can be used to establish consistent stitching holes before sewing with traditional hand-stitching techniques.

Choose between 5mm and 6mm spacing depending on the look and construction of your project.

5mm spacing gives a relatively close stitch pattern and is a versatile choice for many leather goods.

6mm spacing creates a more open stitch pattern and can work particularly well for larger pieces or projects where a more pronounced stitch line is desired.

Choosing the correct spacing is ultimately a combination of leather thickness, thread size, project scale and personal preference.
