Polyester thread is a versatile and widely used material in the world of sewing and crafting. With its numerous benefits and applications, it has become a staple for both professional and amateur sewers alike. In this comprehensive guide, we will delve into the world of polyester thread, exploring its characteristics, uses, and tips for choosing the right thread for your projects.

What is Polyester Thread?

Polyester thread is a type of synthetic thread made from polyester fibers. It is known for its exceptional strength, durability, and resistance to stretching, shrinking, and fading. Polyester thread is available in various thicknesses, commonly referred to as thread weights or denier.

Advantages of Polyester Thread

  • Strength: Polyester thread is highly resistant to breakage, making it suitable for sewing projects that require strong and durable seams.
  • Durability: Unlike natural fibers, polyester thread does not deteriorate over time, ensuring that your creations withstand the test of time.
  • Colorfastness: Polyester thread retains its color even after repetitive washing and exposure to sunlight, making it an excellent choice for garments and items that require frequent laundering.
  • Resistance to Stretching: Polyester thread has minimal stretch, allowing for more precise stitching and preventing unwanted distortion in your finished projects.
  • Affordability: Polyester thread is generally more affordable compared to other types of threads, making it a budget-friendly option for sewers of all levels.

Choosing the Right Polyester Thread

When selecting polyester thread for your projects, there are a few factors to consider to ensure optimal results.

Thread Weight

Polyester thread comes in various weights, typically indicated by a number. The higher the number, the finer the thread. The choice of thread weight depends on the fabric you are working with and the desired outcome.

For lightweight fabrics like silk or chiffon, opt for a fine thread such as 60wt or 50wt. Medium-weight fabrics like cotton or linen work well with 40wt or 30wt thread, while heavier fabrics like denim or upholstery may require thicker threads like 20wt or 10wt.

Color Matching

Choosing the right color is crucial to achieve a seamless finish. Polyester thread is available in a vast array of colors, allowing you to easily find a match for your fabric. If you can’t find an exact match, selecting a slightly darker shade is often a better choice than a lighter one, as it will blend in more effectively.

Quality and Brand

Investing in high-quality polyester thread is essential for optimal results. Established brands often offer superior thread that is less likely to cause tension issues, breakage, or fraying. Popular polyester thread brands include Gutermann, Coats & Clark, and Mettler. Reading reviews and seeking recommendations from fellow sewers can help you make an informed decision.

Applications of Polyester Thread

Polyester thread is suitable for a wide range of sewing projects, owing to its strength and versatility. Here are some common applications:

Garment Construction

Polyester thread is an excellent choice for constructing garments, as it can withstand the stress of seams and stretching. It is particularly ideal for sewing knit fabrics, swimwear, lingerie, and activewear where flexibility and durability are paramount.


Quilters often prefer polyester thread for both piecing and quilting due to its durability and resistance to shrinkage. It creates strong and secure seams, ensuring that the quilt remains intact even after multiple washes.

Home Decor

When creating home decor items such as curtains, cushions, or upholstery, polyester thread is an excellent option. Its colorfastness and resistance to fading make it suitable for items exposed to sunlight, while its strength ensures longevity.


Polyester thread is widely used for machine embroidery due to its sheen, vibrant colors, and ability to withstand high-speed stitching. It adds a professional touch to designs and is compatible with various embroidery machines.

Tips for Using Polyester Thread

To make the most out of polyester thread, consider the following tips:

  1. Always use the appropriate needle size for your thread weight and fabric.
  2. Opt for a longer stitch length when working with polyester thread to prevent tension issues.
  3. When machine sewing, use a polyester thread in both the top and bobbin for optimal results.
  4. Store your polyester thread in a cool, dry place away from direct sunlight to maintain its quality.
  5. For delicate fabrics, test the thread on a scrap piece to ensure it doesn’t cause any damage or leave visible marks.


Polyester thread is a reliable and versatile choice for a wide range of sewing projects. Its strength, durability, and resistance to stretching, shrinking, and fading make it a top choice for both beginners and experts alike. By considering factors such as thread weight, color matching, and quality, you can ensure that you are using the right polyester thread for your specific project. Follow the provided tips to make the most out of this exceptional thread, and let your sewing creations stand the test of time.
