How to Saddle Stitch Leather (Hand-Stitching Basics)

You use one length of thread with a needle on each end. First mark and punch evenly spaced holes along your stitch line. Then, holding the leather in a stitching pony, pass one needle through the first hole and centre the thread. For each hole, push one needle through, then the other needle through the same hole from the opposite side, and pull both snug, keeping tension even and always leading with the same needle. Backstitch a couple of holes at the end to lock it.

Because of how the thread is locked. A saddle stitch fills each hole with thread passing through from both directions, so if one stitch is cut or wears out, the seam stays put and does not unravel. A machine lock stitch uses two separate threads looped together, and if one breaks, the seam can unzip along its length. The saddle stitch is slower to do by hand, but its redundancy makes it more durable, which is why quality leather goods use it.

Only a few: a way to make holes (a set of stitching chisels or a pricking iron plus a mallet, or an awl), two harness needles (blunt needles suited to leather), waxed thread, and ideally a stitching pony or clamp to hold the work. You will also want something to mark your stitch line, like a wing divider or edge groover. It is a low-cost toolkit to begin with, and you can add specialised tools as your projects grow.

Before. You mark your stitch line and then punch all the holes first with a stitching chisel or pricking iron, tapping it with a mallet for evenly spaced, angled slits, and only then do you start sewing. Punching in advance is what gives the stitching its clean, uniform, slanted appearance. Piercing each hole with an awl as you go is the traditional method but much harder to keep even, so beginners usually punch the whole line first with chisels for consistent spacing.

Waxed thread made for leatherwork, such as waxed polyester or braided/linen thread, is standard, the wax helps it grip and stay put and resists fraying. Choose a thickness that suits your project and hole size (finer thread for wallets, thicker for bags and belts). Cut a length roughly four times the length of your seam so you have enough to stitch the whole line with both needles. Match the needle size to the thread and holes so it passes through cleanly.
