A leather stitching pony is a small clamp that holds leather upright while you sew. It leaves both hands free: one to guide the needle and the other to manage the thread and maintain an even tension. The tool need not be elaborate. A stable base, two aligned jaws, a gentle screw adjustment, and soft leather faces are enough for most hand-sewn leather work.
This version is made from hardwood offcuts and adjusted with a threaded screw, washers, and a wing nut. It is compact enough for a small bench, yet broad enough to hold belts, pouches, wallet parts, and other moderately sized work.
Materials and preparation
Choose straight, sound timber for the jaws. Hardwood is preferable because the jaws will be tightened repeatedly, but a dense, clean softwood offcut can serve for a first build. Avoid boards with splits near the screw holes.
For a useful general-purpose size, prepare:
- One base, approximately 300 mm long, 120 mm wide, and 20–25 mm thick.
- One fixed jaw, approximately 300 mm long, 50–60 mm wide, and 20 mm thick.
- One moving jaw of similar size.
- Two small hardwood triangular braces, if the fixed jaw needs extra support.
- Two pieces of vegetable-tanned leather for the jaw faces.
- One threaded rod or long machine screw, with a washer and wing nut that fit it.
- Wood screws, wood glue, sandpaper, and a drill with bits suited to the screw and threaded rod.
The measurements are starting points rather than a pattern. A taller jaw gives more room for large work, while a shorter one takes up less space and may be more comfortable for small pieces. Keep the two jaws the same length and width so their faces meet evenly.
Before cutting, decide where the pony will sit. If it will be used on a bench, the base should be long enough to resist tipping when thread is pulled firmly. If it will be held between the knees, a narrower base may be easier to manage, but it should still have a smooth underside and no projecting screws.

Shape and smooth the wooden parts
Cut the base and jaws squarely. The top edges of the jaws may be left square, or softened with a small chamfer. A chamfer reduces sharp corners that can catch thread or press into the worker’s hands.
Sand every surface that will be touched. Start with a medium abrasive to remove saw marks, then finish with a finer paper. Do not leave roughness on the inside faces of the jaws: it can transfer marks through thin leather or catch a thread while the work is being repositioned.
The fixed jaw should stand upright near one end of the base. Set it slightly back from the front edge so the pony has a broad footprint. Apply glue along the joint, position the jaw carefully, and reinforce it from below or from the sides with wood screws. Predrill all screw holes, particularly near the ends of the timber. This reduces the chance of splitting.
Use a square to check that the fixed jaw is perpendicular to the base. It need not be perfectly vertical for the pony to work, but it should not lean sideways. If the joint feels flexible, add small triangular braces on the outside of the fixed jaw. Keep the inside face clear so the moving jaw can close against it.
Make the moving jaw and hinge
The moving jaw needs to open at its upper end while remaining connected to the base at the lower end. A simple leather hinge is quiet, forgiving, and easy to make with the materials at hand.
Cut two leather hinge straps approximately 25–35 mm wide and long enough to cross the lower joint with a little spare length. Vegetable-tanned leather around 2–3 mm thick is suitable. Position the straps on the outside of the moving jaw and base, one near each side. Screw them firmly to the base and to the lower portion of the moving jaw, using washers beneath the screw heads if needed.
Leave the straps loose enough to flex. They should hold the jaw in position without preventing it from tilting open. Do not place the hinge screws so close to the edge that they can split the wood or pull through the leather. If the moving jaw shifts sideways, add a second strap or use short hardwood side guides fixed to the base.
A wooden pivot can be used instead of leather straps if you prefer a more rigid construction. In that case, drill aligned holes through small side blocks and the lower end of the moving jaw, then use a smooth screw or rod as a pivot. The pivot must turn freely; overtightening it will make the jaw difficult to adjust.
Add the screw adjustment
Close the moving jaw against the fixed jaw and mark a point near the upper third of both jaws. This is where the adjustment screw will draw the jaws together. Keep the hole well inside the edges of the timber and centred across the width.
Drill a clearance hole through the moving jaw. Drill a matching hole through the fixed jaw, sized so the threaded rod or machine screw can pass without binding. The washer and wing nut should sit on the outside of the fixed jaw, where they are easy to reach. If the threaded part is too long, leave the excess projecting away from the work rather than cutting it until the fit has been tested.
The screw should pull the jaws together, not force them out of alignment. Fit a washer beneath the wing nut and, if necessary, another washer on the opposite side to spread the pressure. Tighten the wing nut by hand. It should close the jaws firmly with moderate pressure; a long lever or wrench is unnecessary and risks crushing the timber or the leather being held.
If the jaws do not meet evenly, loosen the screw and inspect the hinge. A slight skew at the lower hinge is usually enough to make the top edges touch on one side first. Correct the strap positions or sand the inside face of the moving jaw very lightly. Remove only enough material to bring the faces into useful alignment.

Fit the leather jaw pads
The leather pads protect delicate leather from dents and give the jaws a little grip. Vegetable-tanned leather is a good choice because it is firm, stable, and easy to cut cleanly.
Cut two strips to match the inside faces of the jaws. They should stop just short of the top and side edges so they cannot curl out of position. Round their corners and sand any hard edge. If the work you sew is especially delicate, use slightly thicker leather or add a second thin layer.
Glue the pads in place with a thin, even coat of wood glue or another adhesive suitable for leather and timber. Keep adhesive away from the very top edge, where it could squeeze onto your project. Clamp or press the pads flat until the adhesive has set, then trim any overhang with a sharp knife, cutting away from your hand and body.
The pads need not be soft like upholstery. Their purpose is to spread pressure and prevent the grain of the wood from marking the leather. If the jaws slip, first check that the pads are clean and that the screw is tightening evenly. Increasing pressure is usually less useful than improving the fit of the faces.
Test the pony and choose a working height
Place a scrap of leather between the jaws and tighten the wing nut gradually. The piece should remain still when you draw a needle and thread through it, but it should not show deep impressions after removal. Thin leather may need only light pressure. Thick layered work can take more, provided the jaws remain parallel and the hinge does not strain.
Set the pony so the stitching line is near a comfortable working height. Many people place the base on the bench and sit so the jaws are around chest or upper-abdomen level. Others hold the base between their knees. The useful position is the one that lets your shoulders remain relaxed and your wrists stay fairly straight while drawing the thread.
If the pony tips when thread is pulled, enlarge the base, add weight beneath it, or clamp the base to the bench. Do not solve instability by tightening the jaws harder. The clamp is meant to hold the work, not serve as a substitute for a stable foundation.

Useful mistakes to avoid
Making the jaws too narrow
Narrow jaws can hold a small wallet panel, but they give little room for repositioning and can twist under pressure. A moderate width makes the tool more forgiving.
Leaving the inside faces rough
Splinters and coarse saw marks can imprint leather. Sand the faces before fitting the pads, and replace a pad if its edge begins to lift.
Using excessive clamping pressure
Over-tightening can crease soft leather, compress a finished edge, or split the timber around the adjustment hole. Tighten only until the work no longer shifts.
Placing the screw too close to the top
A hole near the end grain weakens the jaw and may cause a split. Leave enough wood above the hole for the screw pressure to be spread safely.
Forgetting thread clearance
The needle and thread need room to pass around the work. Keep the upper edges of the jaws neat, and avoid adding bulky pads or braces where they will obstruct the stitch line.
Finishing the tool
Round the outside corners, remove all loose fibres, and wipe away dust. A plain, sanded finish is sufficient. If you apply an oil or wax, keep it off the leather pads and allow the timber to dry fully before clamping leather.
Inspect the screws from time to time. Wood can compress slightly around a joint, and leather hinge straps may settle after use. Retighten only as needed. Replace a worn pad rather than accepting a rough or uneven jaw.
A well-made leather stitching pony is deliberately modest. Its value lies in steadying the work, not in adding complication. Once the jaws hold without marking and the base sits comfortably at hand, the tool becomes a quiet part of the sewing process: both hands remain available, the thread can be drawn evenly, and the stitch line is easier to follow from one hole to the next.
