Use a ladder stitch to re-sew an open or torn seam on leather. The only tools you need are a curved needle, heavy-duty upholstery thread, and needle-nose pliers. Upholstery thread is critical, as regular thread will break in the tightening process.
- Single thread the needle with a knot on one end. Do not double thread in case you have to remove a few stitches.
- Insert your needle into the torn seam and come up through a stitch hole where the original thread remains intact.
- Tie a knot and anchor your thread. Secure any other loose threads or tie them into your new thread.
- If you have not already pulled the needle up through the first stitch hole, do so now. You may need pliers with stiff, old leather.
- Jump across the seam and dive your needle into the hole directly opposite the one you just came through.
- Pull the needle through and come up into the adjacent hole.
- Pull the needle through, jump across the seam again and dive into the next hole.
- Repeat. Leave your thread and stitches loose until the seam is mostly closed. Go back to the beginning and tighten the thread. It may take a couple tightenings to get the best result.
- Finish the last few stitches, securing your thread and any remaining threads.
