How to choose the right thread for sewing lining and interlining?

Dec 02, 2025

Hey there, fellow sewing enthusiasts! As a supplier of lining and interlining, I've seen firsthand how crucial it is to pick the right thread when working with these materials. It can make or break your project, whether you're a seasoned pro or just starting out. So, let's dive into how you can choose the perfect thread for sewing lining and interlining.

Understanding Lining and Interlining

First off, let's quickly go over what lining and interlining are. Linings are the fabrics that go on the inside of a garment, giving it a finished look and adding comfort. They also protect the outer fabric from wear and tear. Interlinings, on the other hand, are used to add structure, shape, and stability to different parts of a garment, like collars, cuffs, and waistbands.

Factors to Consider When Choosing Thread

1. Thread Type

There are several types of threads available, each with its own characteristics. Cotton thread is a popular choice because it's strong, breathable, and easy to work with. It's great for natural fiber linings and interlinings. Polyester thread, on the other hand, is more durable and resistant to stretching and shrinking. It's a good option for synthetic linings and interlinings. Silk thread is smooth and has a beautiful sheen, making it ideal for high - end projects with delicate linings.

2. Thread Weight

Thread weight refers to the thickness of the thread. For lining and interlining, a medium - weight thread is usually a good choice. A lighter weight thread may break easily, while a heavier weight thread can be too bulky and may show through the fabric. You can usually find thread weight information on the thread spool. For example, a 50 - weight thread is a common choice for general sewing of linings and interlinings.

3. Color

The color of the thread should match or blend well with the lining or interlining fabric. If you're using a light - colored lining, a white or off - white thread is a safe bet. For darker linings, black or a matching dark color thread will work. Sometimes, you might want to use a contrasting thread for a decorative effect, but that's more of a creative choice.

4. Compatibility with the Fabric

It's important to consider the type of fabric you're using. If you're working with a slippery lining fabric, like satin, you'll need a thread that can hold up well without slipping. A polyester or silk thread might be a better option in this case. For a thick interlining, a stronger thread like a heavy - duty cotton or polyester thread will be necessary to ensure a secure stitch.

Specific Thread Recommendations for Different Types of Lining and Interlining

1. Silk Linings

Silk linings are delicate and require a thread that won't damage the fabric. Silk thread is the top choice here. It has a similar texture to silk fabric, so it won't cause any abrasion. A fine - weight silk thread, like a 60 - weight, will give you a smooth and invisible stitch. If silk thread is not available, a very fine polyester thread can also work, but make sure it's soft and doesn't have a rough texture.

2. Cotton Linings

Cotton linings are more forgiving and can work well with cotton thread. A 50 - weight cotton thread is a great all - around option. It's strong enough to hold the lining in place and has a natural look that complements cotton fabric. You can also use a polyester - cotton blend thread, which combines the strength of polyester with the softness of cotton.

3. Synthetic Linings

Synthetic linings, such as polyester or nylon, are often slippery and require a thread that can grip well. Polyester thread is the way to go. It's strong, resistant to moisture, and won't stretch or shrink like cotton thread might. A 40 - weight polyester thread is a good choice for most synthetic linings.

4. Woven Adhesive Interlining

When working with Woven Adhesive Interlining, you need a thread that can withstand the heat used in the fusing process. A high - quality polyester thread is recommended. It can handle the heat without melting or losing its strength. A medium - weight polyester thread, like a 50 - weight, will work well for sewing this type of interlining.

5. Microdot Fusible Woven Fusing Interlining

Microdot Fusible Woven Fusing Interlining is a bit more delicate. A fine - weight thread is needed to avoid damaging the microdots. A 60 - weight silk or polyester thread can be used. These threads are thin enough to sew through the interlining without disrupting the fusing dots.

6. Woven Fusible Warp Knitted Interfacing

For Woven Fusible Warp Knitted Interfacing, a thread that can handle the stretch and structure of the interfacing is required. A polyester - cotton blend thread is a good option. It combines the stretchability of cotton with the strength of polyester. A 50 - weight blend thread will provide a good balance.

Tips for Sewing Lining and Interlining

  • Test Stitches: Before you start sewing your project, do a test stitch on a scrap piece of the lining or interlining fabric. This will help you see how the thread behaves and if it's the right choice.
  • Use the Right Needle: Make sure you're using the appropriate needle for the fabric and thread. A fine needle is usually better for linings and interlinings to avoid leaving large holes in the fabric.
  • Stitch Slowly: Take your time when sewing lining and interlining. Slow stitching will give you more control and help prevent mistakes.

Conclusion

Choosing the right thread for sewing lining and interlining is an important step in any sewing project. By considering factors like thread type, weight, color, and compatibility with the fabric, you can ensure a successful outcome. Whether you're working on a simple blouse or a complex suit, the right thread will make your garment look professional and last longer.
