Available in extra-large 1,094-yard spools, this high-quality thread is ideal for use with any fabric and any sewing machine.

Serger thread is used to create seams and finish raw edges, therefore its flexibility, strength, and lack of bulk are essential.

Having 10 yards of polyester thread per spool is sufficient for many routine mending tasks. This thread should only be used by hand and not in a sewing machine.

Can You Sew Leather With Linen Thread?

The use of linen thread is recommended for hand stitching leather. Typically, this type of thread can be found in leather goods like boots, holsters, saddles, and totes.

In spite of the fact that linen is constructed from cotton fibers, it may be suitable for leatherwork. However, you should count on linen thread not being as long-lasting as the best leather thread.

Instead, if you’re sewing leather for looks, linen thread is your best bet. Linen thread, with its natural look and feel, complements leather exceptionally well.

How Do You Sew Leather Thread?

  • When stitching along a leather seam, it is important to conceal the first knot of the needle and bobbin thread between the layers of leather. This will give the seam a more professional and seamless appearance.
  • To avoid thread breaking, it’s important to use the right size needle for the leather you’re working with (e.g., lighter weight threads for decorative stitching and heavier weight threads for areas that will be worn quickly)
  • Nylon thread in sizes #46 and #69 are commonly used for sewing leather goods, while size #138 thread is often used for upholstery.
  • When sewing, make sure you’re using a needle that’s appropriate for the size of thread you’ve chosen.
  • To avoid shredding the leather due to unequal tension, use a longer stitch length when working with thick leather threads.

What Do You Use To Sew Leather Together?

The leather can be stitched using nylon, polyester, or linen thread. When sewing leather, however, there are two additional considerations.

What size of thread for sewing leather

Leather thickness determines the appropriate thread size. Therefore, heavier leather, or leather that will get worn fast, will need to be sewed using a larger size thread to ensure it can handle the pressure.

Keep in mind that not all threads are created equal in terms of their diameters. However, if you want a quick idea, just think about the thread’s measurement in millimeters and keep in mind the chart below:

  • Thread sizes between 46mm and 138mm are suitable for sewing the thin leather used for many wallets and handbags.
  • Thread sizes between 138mm and 554mm are suitable for sewing the medium-weight leather used for bags.
  • The thick, boot-quality leather typically utilized for its stitching may accommodate a thread size of 207 mm or more.

What color of thread for sewing leather

For leather, the choice of thread color is purely aesthetic. While a darker shade may be preferred by some, a lighter one may be more functional and prevent the item from becoming dirty. A contrast may be preferred when it comes to highlighting details, such as the white thread on leather.

Black or brown threads are usually a safe bet, but ultimately the choice is up to the sewer. Think about the overall feel and design of your leather project, or test the thread out against the leather to see how it looks.

What Size Needles For Hand Sewing Leather?

When working with heavyweight materials like leather, however, using a sewing machine is the quickest and most efficient option. However, hand sewing leather is still doable for minor repairs and DIY projects.

Differences In Sewing Thread

Leather needles range in size from 2 to 10, and finding the right one for your project is entirely dependent on the sort of leather you’re working with. A leather needle, which can also be used for pleather, suede, and vinyl, can be recognized by its triangular shape and its ability to cut and enter the material.


Finally, the end! The type of thread being used is an important factor in determining the optimal thread for sewing.

Threads can be further categorized according on their construction and finish and can be crafted from either synthetic or natural fibers. Pick a thread size and color that complements your needle and fabric.
