John James Saddlers Harness Needles - Rounded Point - 25 Pack, Size 002 - Medium Review (2026)

What these needles are

John James is a long established English needle maker, and this listing is a 25 pack of their saddlers harness needles in size 002, a medium size measuring 54mm in length and 1.02mm in diameter. These are rounded point needles, meaning the tip is blunt rather than sharp, which is the standard style for saddle stitching since the technique relies on pre-punched holes from a stitching chisel or awl rather than the needle piercing the leather itself. A rounded tip also reduces the risk of splitting the thread or catching the leather fibers awkwardly as the needle passes back through an existing hole, which matters when two needles are worked from opposite sides of the same stitch line, the defining technique of hand saddle stitching.

Sizing and what it works with

At 1.02mm diameter and 54mm length, size 002 sits in the medium range of the John James harness needle lineup, which runs from finer sizes for lightweight thread up to larger sizes built for heavier cord. This size pairs well with mid-weight waxed thread commonly used for wallets, small bags, and general leathergoods stitching, giving enough eye clearance for typical thread thicknesses without being so large that it stretches small stitch holes. Crafters working with notably thicker thread, such as heavier linen or waxed nylon used on belts or harness repair, may find this size a tighter fit through the eye and should size up, while very fine decorative stitching on thin leather may call for a smaller needle than this one.

Using them for saddle stitching

Because the point is rounded rather than sharp, holes need to be made first with a diamond stitching chisel, a pricking iron, or an awl before the needle is worked through, which is standard practice for saddle stitch and is not a limitation specific to this needle. The technique uses two needles, one threaded on each end of a single length of waxed thread, passed through the same hole from opposite sides and pulled snug to lock each stitch in place, which is what gives saddle stitching its strength compared with a single-thread running stitch. A 25-needle pack gives plenty of spares for a technique where needles occasionally bend, especially with repeated stitching through thick or heavily cased leather, or simply get lost during a project.

How this size compares with other John James sizes

Compared with a smaller size like 004, which has a narrower diameter for fine thread and delicate stitching, size 002 handles noticeably heavier thread without the eye becoming a bottleneck. Against a larger size such as 0 or 1/0, covered elsewhere in this guide for heavier harness and tool roll work, size 002 is easier to work through smaller, tighter stitch holes typical of wallets and slim goods, though it will feel undersized for thick harness-weight cord. Picking the right size mostly comes down to matching needle diameter to the thread you are using, since a needle that is too large for the thread wastes hole size, while one that is too small makes threading and pulling the eye through leather harder than it needs to be.

Who should buy this size

Size 002 is a solid general-purpose choice for hobbyists and small-goods makers working with typical mid-weight waxed thread on wallets, pouches, and light bags, since it splits the difference between the finest and heaviest sizes in the John James range. It also suits anyone who already owns a stitching chisel or awl and wants a reliable, well-regarded needle brand for regular saddle stitch projects, given the reputation John James needles have among hand stitchers. Skip this specific size if your projects lean toward either very fine decorative work, where a smaller needle threads more easily, or heavy harness and tool roll repair with thick cord, where a larger size like 0 or 1/0 will handle the thread more comfortably.
