Description

John James has manufactured needles in England since 1840. The L3912 saddlers harness needle is their standard for hand-stitched leatherwork — a blunt-point, large-eyed needle designed specifically for passing waxed thread through pre-punched stitch holes in leather. The blunt point is deliberate — it follows the hole rather than piercing the leather, producing a clean stitch without splitting fibres at the edge of the hole.

These are the needles used in traditional saddle stitching and hand leatherwork worldwide. Each pack contains 25 needles in a sealed packet.

Key Details

  • Made in England by John James since 1840
  • L3912 series — the leathercraft industry standard
  • Blunt point for clean passage through pre-punched holes
  • Large eye for easy threading with waxed thread
  • Pack of 25

Choosing the Right Size

  • Size 001 – 54mm × 1.02mm: Slightly larger eye for easier threading with heavier thread. Useful when working with thicker waxed thread or when double-threading.
  • Size 002 – 54mm × 1.02mm: The standard general-purpose choice for most hand leatherwork. A practical starting point for most makers.
  • Size 004 – 48mm × 0.86mm: Finer needle for detailed work, lighter thread gauges and fine leather goods such as wallets and watch straps.

These needles are sized for use with waxed polyester and linen thread in the 0.45mm to 0.65mm range. We stock Artisan Soul 0.55mm waxed polyester thread in 35 colours — a direct match for everyday use with size 001 and 002.
