Sewing on Leather

Bonded Nylon Thread

One of the most popular and reliable choices for sewing on leather is bonded nylon thread. It is made from continuous filaments of nylon, which are bonded together for added strength and durability. Bonded nylon thread is resistant to abrasion, UV rays, mildew, and chemicals, making it ideal for long-lasting leather projects.

At Thread Art, we offer heavy duty bonded nylon threads in size 69 suitable for various leather applications. These threads are available in several different colors, allowing you to choose the perfect match for your project.

Did you know? Bonded nylon thread is commonly used in automotive upholstery, leather garments, handbags, and shoes due to its exceptional strength and resistance to wear.

Polyester Serger Thread

Another excellent option for sewing on thinner leather is polyester serger thread. Polyester threads are known for their strength and resistance to stretching and shrinking. They also have good colorfastness, meaning they won't fade easily over time. Polyester threads are available in a wide range of colors, giving you the flexibility to match or contrast with your leather project.

When working with leather, it is important to select a polyester serger thread with a high tensile strength to ensure the stitches hold up under pressure. 

Embroidering on Leather

Embroidery adds a beautiful and intricate touch to leather projects, and polyester machine embroidery thread is an excellent choice for achieving stunning results. Here's why:

Strength and Durability

Polyester machine embroidery thread is renowned for its strength and durability. When embroidering on leather, it's crucial to use a thread that can withstand the tension and pressure created by the embroidery machine. Polyester thread is up to the task, as it is designed to handle high-speed stitching without breaking or fraying.

Vibrant Colors

Polyester machine embroidery thread is available in a vast array of vibrant colors, allowing you to bring your creative vision to life. Whether you want to add colorful patterns, intricate designs, or personalized monograms to your leather projects, polyester thread offers a wide range of options to suit your style and preferences.


Leather products are often exposed to sunlight and various environmental factors. It's important to choose a thread that can withstand these conditions without fading or losing its color over time. Polyester machine embroidery thread is known for its excellent colorfastness, ensuring that your embroidered leather creations retain their vibrant hues for years to come.


Polyester machine embroidery thread is suitable for a variety of leather projects, including bags, jackets, shoes, and accessories. It can be used to create both bold and intricate designs, allowing you to customize your leather items with intricate logos, patterns, or text.

When embroidering on leather, it's important to choose the appropriate stabilizer and hooping technique to ensure smooth stitching and prevent any damage to the leather surface. It's also advisable to use a sharp embroidery needle specifically designed for leather to ensure clean and precise stitches.

At Thread Art, we offer a wide selection of polyester machine embroidery threads in various colors, thicknesses, and finishes. Explore our collection to find the perfect thread to elevate your leather embroidery projects.

Pro Tip: Before embroidering on a piece of leather, it's recommended to test the design and thread on a scrap piece of the same leather material. This allows you to adjust the tension, needle size, and stitch density for optimal results.

Choosing the Right Thread for Your Leather Project

Selecting the appropriate thread for your leather project depends on several factors, including the thickness of the leather, the type of stitching, and the desired aesthetic.

If you're working with thick and heavy leather, such as for furniture upholstery or motorcycle accessories, bonded nylon thread is an excellent choice due to its exceptional strength and resistance to wear.

On the other hand, if you're sewing on lightweight or delicate leather, polyester serger thread might be a better option as it offers good strength while maintaining a more refined appearance.

Embroidering on leather with polyester machine embroidery thread opens up a world of creative possibilities. The strength, vibrant colors, colorfastness, and versatility of polyester thread make it an excellent choice for adding beautiful and intricate designs to your leather projects.
