The Ultimate Guide to Sewing Thread: Types, Uses, and Tips

When it comes to sewing, fabric and patterns often take the spotlight—but thread is just as essential. Choosing the right type of sewing thread can make the difference between a garment that lasts and one that unravels after a few washes. In this post, we’ll explore the different types of sewing thread, their common uses, and how to choose the best one for your project.

Why Thread Matters

Thread is what holds your fabric together when you are sewing! The strength, elasticity, thickness, and fiber content of the thread affect your stitch quality, fabric behavior, and the overall durability of your finished item. Using the wrong type of thread can lead to puckering, broken seams, or skipped stitches. Check out some different types of threads below and examples of each! Note: I may make a small commission from my Amazon storefront and links in this blog post.


Common Types of Sewing Thread

1. Cotton Thread

  • Best for: Light to medium-weight natural fabrics like cotton or linen.

  • Properties: Soft, low stretch, matte finish.

  • Pros: Breathable, ideal for vintage projects or quilting.

  • Cons: Not suitable for stretchy or heavy-duty materials.

2. Polyester Thread

  • Best for: Most general-purpose sewing.

  • Properties: Strong, slightly stretchy, smooth texture.

  • Pros: Versatile, works well with synthetic and natural fabrics.

  • Cons: Can melt under high heat (e.g., when pressing seams with a hot iron).

  • Example: Singer All Purpose Polyester Thread

3. Cotton-Wrapped Polyester Thread

  • Best for: Everyday sewing with a bit more durability.

  • Properties: A polyester core with a cotton outer wrap.

  • Pros: Has the strength of polyester with the look of cotton.

  • Cons: Slightly more expensive than pure cotton or polyester threads.

  • Example: Coats & Clark Cotton Covered Quilting Thread

4. Nylon Thread

  • Best for: Upholstery, outdoor gear, leather, and heavy fabrics.

  • Properties: Very strong, elastic, smooth.

  • Pros: High tensile strength and stretch.

  • Cons: Can be too thick for regular sewing machines.

  • Example: Gutermann Invisible Thread

5. Silk Thread

  • Best for: Delicate fabrics and hand sewing.

  • Properties: Smooth, luxurious, slightly elastic.

  • Pros: Perfect for fine fabrics like silk or wool, ideal for tailoring.

  • Cons: Expensive, not great for everyday sewing.

  • Example: Clover Silk Thread

6. Metallic Thread

  • Best for: Decorative stitching and embellishments.

  • Properties: Shiny, often mixed with polyester or nylon.

  • Pros: Eye-catching; great for special projects.

  • Cons: Can be finicky in machines and prone to breaking.

  • Example: Coats & Clark Metallic Thread

Specialty Threads

  • Topstitching Thread: Thicker, used for decorative seams.

  • Elastic Thread: Used for shirring and gathering. I have a whole video on using elastic thread when I made a silk top with some shirring! See it here: DIY Silk Shirt

  • Invisible Thread (Monofilament): Clear nylon or polyester for invisible stitching. 

  • Quilting Thread: Made specifically for quilting, often stronger and smoother.


Tips for Choosing the Right Thread

  1. Match the thread fiber to the fabric fiber. For example, use cotton thread with cotton fabric.

  2. Check the thread weight. Thicker thread is better for visible topstitching; finer threads are great for delicate seams.

  3. Test on scrap fabric. This helps prevent surprises with tension or appearance.

  4. Use quality thread. Cheap thread can fray, snap, or damage your machine.
