How to Hand-Stitch Leather With a Saddle Stitch

To hand-stitch leather, mark a stitch line, punch evenly spaced holes, then sew a saddle stitch: one waxed thread with a needle on each end, both needles passing through every hole from opposite sides. Finish with a backstitch and tap the stitches flat with a smooth hammer. You need no machine, only a few tools and patience.

This tutorial is part of our leathercraft techniques and garment construction section, alongside debossing and hand embroidery.

Why the saddle stitch

The saddle stitch makes two interlocking lines of thread, so each stitch locks on its own. If one thread breaks, the rest of the line holds. A machine lockstitch interlocks an upper and a bobbin thread inside the leather instead.

Tandy, Goldbark and Weaver all say the saddle stitch is stronger or more secure than a machine stitch. That is the view of makers and suppliers; we found no independent seam test. Other hand stitches (running, cross, baseball) are compared in common leather stitching types.

Tools and materials

Where makers disagree

Leather suppliers teach slightly different rules. None is wrong; pick one and stay consistent.

How to hand-stitch leather, step by step

1. Mark the stitch line

Set a groover to 1/8 in from the edge and run it along the front. The groove keeps the line straight and lets the thread sit below the surface. On parts that see little friction, a wing divider mark is enough.

If you are joining two layers, glue them first with leather glue on clean, dry, roughened surfaces.

2. Punch the holes

Set the chisel in the groove on a poly cutting board and strike it with a rawhide mallet. Place the first tine in the last hole you made before each strike, so spacing stays even. Keep the chisel upright and rock it gently to pull it out; a little beeswax helps.

With a pricking iron, strike only to mark and cut the surface, then open each hole with the awl as you sew.

3. Cut the thread

Measure the stitch line and cut 3.5 to 5 times that length. Thicker work takes more. If a long thread tangles, sew a few inches, tie off and start again.

4. Lock a needle on each end

Thread a needle onto each end. With linen or hemp, wrap the thread back on itself a few times so it cannot slip; with woven poly, one loop is usually enough.

5. Clamp the work

Clamp the piece in a stitching pony with the holes facing up and away from you. Start at the hole farthest away and stitch toward yourself.

6. Make the first stitch

Pass one needle through the first hole and pull until the thread is even on both sides.

7. Saddle stitch the line

At the next hole, push the front needle in, then push the back needle through the same hole from the other side, and pull both through. Tandy's saddle stitching method adds a wrap of the thread over the second needle to lock each stitch and set the slant. Keep the same order at every hole so the slant stays uniform.

Pull both threads with the same tension each time. Repeat to the last hole.

8. Lock the end

Backstitch two to four holes, passing back through holes you have already sewn. Or bring both threads to the back and tie a square knot. Trim poly thread about 1/8 in from the surface and melt the end; put a drop of glue in the last hole for linen or hemp.

9. Set the stitches

Tap the stitch line with a smooth-faced hammer or maul. This closes the holes, sinks the thread into the groove and reduces wear.

Corners

On a curve or corner, switch to a 2-tine chisel to mark and a single-tine chisel to punch, one hole at a time. For matching rounded corners on two layers, glue the face piece to the backing and cut the backing using the face as a guide; groove the front only. If the last holes do not fit, use the single tine to spread or tighten the spacing gradually.

Check your stitch line

A good line is something you can check by eye and finger:

• Spacing. Every gap the same; this comes from the chisel, not the needle.
• Slant. Every stitch leans the same way.
• Height. After hammering, you should barely feel the thread.
• Stitch size. Count stitches per inch: divide 25.4 by the chisel spacing in mm. A 3 mm iron gives about 8.5 per inch (Sailrite's glossary shows the sum), and smaller stitches are generally seen as finer work.

The same checks work on a jacket or bag you are thinking of buying.

Common mistakes

Buying instead of making

If you would rather buy than sew, Leather Collection men's leather jackets are made to order in cowhide, sheepskin, lambskin or goatskin. Ask which seams are sewn by hand and which by machine before you order, and check the stitch line with the list above.

FAQ

Can leather be sewn by hand?

Yes. The saddle stitch needs only two needles, waxed thread and pre-punched holes. Small items such as journal covers, holsters and sheaths can be made at a table, as Weaver shows.

Can I stitch leather with a normal sewing machine?

Often, with the right leather needle; see leather stitching: stitches, tools and construction basics for needle sizes and limits.

How can I join two pieces of leather together?

Glue the layers, then saddle stitch through both. For edges laid side by side, a cross or baseball stitch joins them.

How long does hand stitching take?

It is slower than machine sewing. One Weaver leathercrafter says he sews about 2.5 in (6 cm) per minute with practice.
