How to Stamp Leather with a Custom Maker's Mark

A maker's mark is the last thing you put on a piece and the first thing people look for. A crisp, even impression says the work was done with care. A faint or smeared one undoes a lot of good stitching. Here's how to get a clean mark every time.

1. Use vegetable-tanned leather

Stamping only works on vegetable-tanned leather. Veg-tan compresses and holds a shape when it's damp, then keeps that shape as it dries. Chrome-tanned leather springs back, so the impression fades within minutes. If you're not sure what you have, dampen a scrap and press a fingernail into it. If the mark stays, it will take a stamp.

Firmer, thicker veg-tan (5 oz and up) takes the deepest, sharpest marks. Thin or soft leather still works, but keep the pressure lighter so you don't cut through or distort the piece.

2. Case the leather

"Casing" means dampening the leather so the fibers are ready to take the impression. It's the step that makes or breaks the mark.

1. Wet a sponge with clean water and wipe it evenly over the grain (the smooth side) where the mark will go. Some makers also dampen the back.
2. Wait. The leather darkens when wet. When it starts returning to its natural color and feels cool to the touch but not wet, it's ready. On most leather that's 5 to 15 minutes.
3. If it dries out too far, wipe it again and wait a little less.

Too wet and the mark goes soft and mushy. Too dry and the leather resists and the mark comes out faint.

3. Work on a hard, flat surface

Any bounce in the surface soaks up force and blurs the edges. Put a granite or marble slab on a solid bench, not a folding table. Lay the leather flat, grain side up.

4. Press or strike

With a press (most repeatable): an arbor press or stamping press gives the same pressure every time, which is what you want when you're marking a run of wallets or belts. Center the stamp, bring the ram down in one smooth pull, hold for a second, and release.

With a mallet: hold the stamp straight up and down and give it one firm strike with a poly or rawhide mallet. Don't tap it several times. Every extra hit risks the stamp shifting and leaving a double edge. If one strike isn't deep enough, the leather is probably too dry or the surface is too soft.

Either way, test on a scrap of the same leather first. It takes two minutes and saves a finished piece.

5. Let it dry, then finish

Leave the piece flat until it's fully dry so the impression sets. Then dye, oil, or finish as usual. Dye settles into the recessed mark and makes it stand out even more.

Troubleshooting

• Faint mark: leather too dry, not enough pressure, or a soft surface underneath. Re-case, and move to a stone slab.
• Blurry or soft edges: leather too wet, or the stamp moved. Let it dry a bit longer and use one strike or one smooth press.
• Deep on one side, faint on the other: the stamp was tilted or the surface isn't flat. Check that the stamp face sits flat before you strike.
• Double image: the stamp bounced or was hit twice. One strike only.

Caring for your stamp

Our maker's marks are solid Delrin (acetal), a tough engineering plastic that doesn't absorb water, so wet leather won't swell or warp it. Wipe it dry after use and store it face up so the design edges aren't knocked. It's made for cold pressing. Don't heat it.

Getting your mark made

Send us your logo or mark in almost any format and we'll check it for line weight before we engrave, so fine details hold up in leather. Every order gets a digital proof at the exact size first. See the Artwork Guide for the details.
