Craftsman who uses thread to sew leather

If you want to make durable leather accessories, it’s important to know what kind of thread to use. Depending on the intended use of the leather article, different types of yarn may be recommended. Whether you’re working on simple or more complex projects, the choice of leather thread can make all the difference.

In this article, we’ll explain how each type of wire works. Leather sewing thread lets you create a multitude of successful, large-scale creative projects. By investing in quality sewing thread, you can give life to timeless leather pieces that last over time.

The different thread materials for sewing leather

Threads can be made of different materials (linen thread, polyester thread, nylon thread, etc.) and each material may not be suitable for all types of leather. So, to obtain a strong, high-quality finished project, it’s essential to use a thread whose composition is compatible with the leather used.
For example, a thick leather will require a strong thread, while a thin imitation leather will need a finer thread to avoid wrinkles.

Wires differ in composition, thickness and strength, and it’s important to take these factors into account when selecting a wire.

There are three main families of thread used for leather sewing:

  • Flax yarn: 100% natural. Most frequently used for leather goods
  • Polyester thread: commonly used for sewing machine sewing.
  • Nylon thread (polyamide): used for projects requiring high strength and a meticulous finish.

Within these three main families of yarns, there are other specific features that can influence the characteristics of the yarns selected, such as:

  • Woven linen yarn: reinforced and waterproof. Resists wear and tear and humidity.
  • Waxed braided polyester yarn: rot-proof.
  • Waxed, fish-glazed or glazed threads: all the thread fibers are glued together with beeswax, making them easier to use during sewing.
  • And also, twisted, cabled, carded or braided yarns and many others ….

By using the right sewing techniques and threads, common problems such as creasing and fraying can be avoided. You authorize stronger, more durable seams that stand the test of time. Thinner threads are better suited to fine, supple leathers, for more discreet, aesthetic stitching, while thicker threads are better suited to thick, stiff leathers.

Choosing the right thread for your leather sewing method

Linen, polyester and nylon/polyamide yarns are popular, and their finish (such as braided, twisted, cabled, potted or glazed) varies according to use and desired result, whether for seams or topstitching.

Wire diameter should also be chosen according to the task in hand. For small leather goods projects, or for assembly of larger, thicker parts, such as luggage. So, depending on whether you’re sewing by hand or by sewing machine, you’ll need to opt for different threads.

Twisted linen thread is a common choice for hand-stitching leather, particularly for saddle-stitching, due to its strength and rigidity achieved through a beeswax-glazed finish.

For machine stitching leather, polyester and nylon (polyamide) threads are often preferred because of their high resistance to breakage and UV.

Finally, woven linen thread is often used with the automatic awl. A hand sewing tool that allows leather to be sewn quickly and automatically.
