A stronger and longer-lasting thread is needed for sewing leather than when sewing fabric. The size, color, material, and stitching method all have an impact on the type of thread that is used while sewing leather. The type of thread used to sew leather-related products will be determined by these factors.

What Thread For Sewing Leather

Types of Leather Thread

Stitching leather together typically necessitates the use of leather thread. Thus, there are a wide range of applications for thread. Let’s take a closer look at some of the best threads out there.

Waxed Polyester

The wax on the thread makes it stronger, so it moves less on the leather, and it’s more resistant to wear, dampness, filth, and other impurities than unwaxed thread. Polyester thread is a robust, lightweight, and long-lasting thread made primarily from plastic. They come in a wide range of hues.

Waxed Linen

Thread created from linen is made from cotton fibers that are both natural and organic. It has a distinctive appearance and feel, making it an attractive choice for some applications. Unlike polyester and nylon thread, linen thread is more suited to hand stitching than machine sewing since it is weaker and more delicate. When wax is added to linen thread, it strengthens and prolongs its life. There are numerous hues of waxed linen thread to choose from.

Bonded Nylon

Polyester thread is “bonded” together into a single strand of bonded nylon thread. The bonded nylon thread strengthens and extends the life of polyester thread for leather by fusing polyester fiber strands together. For leatherworking, this is a preferred thread for both machine and hand sewing. Many hues of bonded nylon thread are available.

However, when it comes to leatherwork there are just a few, if not the most reliable of threads available. Let’s find out which ones are the greatest and compare them.

Type of thread used for sewing leather

When sewing leather, you must use a thread that will hold the leather together when you apply pressure to it. This is why nylon and polyester are the two most commonly utilized threads when working with leather that has been bonded.

Because of its affordability, ease of use, and outstanding performance, nylon is the most sought after material. Polyester, like nylon, is resistant to mildew and ultraviolet rays, making it more durable than nylon.

The threads can be waxed or unwaxed, depending on preference. Waxed thread can clog and jam sewing machines, therefore avoid using it while sewing by hand.

Waterproof and rot-resistant, pre-waxed thread can aid to keep the fabric from expanding. As a result of its bond, it will endure longer.

Hemp, linen, and cord threads of the same length do not have the same strength, hence these are the two most usually used. Wrapping the thread between your hands and attempting to break it with a tug is a good approach to test its tensile strength. If you’re using a high-quality thread, this will be extremely tough, if not impossible.

I would always choose a pre-waxed thread for an uninvolved seem and a smooth to glide through the holes. If you’re planning on using machines, you are able to use your personal wax on the thread, which can prolong the life of you seem to.

If you want a clean, uncomplicated look, I recommend using a pre-waxed thread. Use your personal wax on the thread to extend the life of the thread if you want to use machines.

Nylon and polyester threads are available on spools for sewing machines and can be utilized in that way.

Tips for Choosing the Best Thread for Sewing Leather

When it comes to stitching on leather, SuperiorThreads recommends using a nylon thread. Stitching leather calls for the use of bonded nylon thread since the bonding process lowers sewing friction and prevents the thread from unraveling.

In the “Waxed Thread Guide,” TheThreadExchange provides a list of the waxed linen threads that can be used for hand-sewing leather. There is a reason why waxed linen thread can be used to stitch leather. It is not only secure, but it is also resistant to a wide range of conditions, including seam tension and water exposure.

Because the wax might clog the needle and other parts of the machine in the treading path, this thread is normally not suitable for sewing.

Make sure you choose the appropriate thread thickness for the leather when choosing a thread for your sewing job. There are many different diameters of nylon thread, so it’s important to consider the recommendations of your fabric while making your selection.

Other Tips for Sewing With Leather

If you’re going to sew leather, the first thing you should do is pick the correct thread for the job. With that said, there are numerous ways you may ensure that your sewing projects are as straightforward as possible!

  • A range of options are discussed in Simon and Louise’s CreatesSpaceAdelaide post, “Tips for stitching leather on your standard home sewing machine,” if your presser foot is not feeding your leather into your machine properly:
  • You might begin by using a [T]eflon foot. Non-stick feet and ultra-glide feet are other names for this type of foot. ” Leather (or faux leather, [PVC], and similar materials) can glide over these types of Teflon feet without adhering to the foot.
  • “Second, you might want to consider using a roller foot… With the help of three rollers (one large and two smaller), you can regulate the movement of the leather and guide it beneath your foot while you sew,” says a sewing expert.
  • “Third, you might want to consider using a walking foot… In order to feed the leather evenly through the machine while you sew, this one comes with its own feed dogs that function in conjunction with the machine’s own feed dogs.”
  • Always use a needle designed for leather sewing. They can pierce the fabric more easily.
  • Leather, unlike other textiles, retains all of the holes you cut into it. Leather becomes increasingly brittle the more holes you make in it. Reduce the number of holes you punch in your leather if you can…
  • Kelly Ralph, in her NationalSewingCircle article “Tips for Sewing with Leather,” recommends using binder clips or paper clips to attach your sewing project.
  • Use a knot instead of a backstitch to keep your thread in place.


Rather than backstitching, tie a knot in your thread.
