How to Hand Sew Leather Welts Using Wire Needles and Waxed Thread

Hand sewing leather welts is one of the most satisfying and durable methods of attaching a shoe’s upper to its sole. Used by traditional shoemakers and cobblers for centuries, the technique relies on wire needles and waxed thread to create a tight, locked stitch that outlasts machine alternatives. This guide walks you through the full process.

What you’ll need

  • 2 steel wire needles
  • Waxed thread (braided, ready-waxed)
  • A welting awl or stitching awl
  • Beeswax or sticky wax
  • Sharp scissors or knife

Making your bristle threads

Wire needles don’t thread like conventional needles — instead, the thread is attached by creating a bristle end:

  1. Cut your required length of thread for the sewing work.
  2. Using a sharp knife, taper the ends of the thread for approximately 7cm.
  3. Using a pointed tool, begin to separate the tapered threads into two strands.
  4. Apply wax to the two strands.
  5. Pass the two strands in opposite directions through the eye of the needle.
  6. Tie a knot using the two strands and the thread.
  7. Twist the tapered strands onto the main thread.
  8. Apply sticky wax to bind the tapered ends firmly to the main thread.
  9. Repeat for the second needle.

Sewing the welt — step by step

  1. Prepare your awl holes — use a welting awl to pierce through the welt and insole at even intervals, typically 5–6mm apart.
  2. Start your stitch — push the first needle through the first hole from left to right, pulling through until equal thread remains on both sides.
  3. Cross stitch — push the second needle through the same hole from right to left, crossing over the first thread inside the hole. This locks each stitch.
  4. Pull tight — pull both needles firmly and evenly to seat the stitch. The waxed thread grips the leather and holds tension.
  5. Advance — move to the next awl hole and repeat, maintaining consistent tension throughout.
  6. Finish — on the final stitch, pass both needles back through the last two holes and tie off securely. Apply a little wax to seal.

Tips for best results

  • Keep your thread waxed throughout — it reduces friction and helps the thread grip.
  • Work on slightly damp leather for easier awl penetration.
  • Consistent tension is key — uneven pulling creates a wavy stitch line.
  • Our hand sewing kit includes 2 wire needles and 10m of ready-waxed thread — everything you need to get started.
