How Do You Make Fabric More Stiff?

When it comes to making fabric more stiff, one effective method is to use interfacing. Interfacing is a layer of fabric placed between the main fabric and the lining to add structure and support. It can make a significant difference in the drape and appearance of the final garment or project.

Choosing the right weight interfacing is essential for achieving the desired level of stiffness. The weight refers to the thickness and sturdiness of the interfacing. Generally, the heavier the weight, the stiffer the fabric will become.

For lightweight fabrics like silk or chiffon, a lightweight interfacing is recommended. This will provide some structure without overwhelming the delicate fabric. It’s important to choose an interfacing that’s compatible with the main fabric, ensuring that they work together harmoniously.

Medium weight interfacing is suitable for fabrics like cotton or linen, as it adds more body and stability without making the fabric too stiff. It’s a versatile option that can be used for a wide range of projects.

Heavyweight interfacing is ideal for fabrics that require a significant amount of structure, such as wool or denim. This weight of interfacing is capable of providing substantial support and can completely change the character of the fabric.

One popular choice for achieving stiffness in fabric is the Madeira Aerolock Premium Serger thread. This thread is specifically designed for sergers and overlock machines, offering superior durability and strength. It’s made of 100% core-spun polyester, ensuring it’s ability to withstand frequent washes and strain.

The Madeira Aerolock Premium Serger thread is particularly well-suited for use in coverlock machines like the Janome CoverPro family. These machines are known for their ability to create professional-grade finishes, and the use of top-quality thread such as the Madeira Aerolock can further enhance the quality of the final results.

Different Types of Interfacing Materials and Their Effects on Fabric Stiffness.

Interfacing is a material used in sewing projects to add structure and support to fabrics. It comes in various types and weights, each with it’s own effect on fabric stiffness.

Fusible interfacing is commonly used and has adhesive on one side that melts when heat is applied, creating a bond with the fabric. It adds moderate stiffness and is suitable for lightweight to medium-weight fabrics.

Non-fusible interfacing, on the other hand, needs to be sewn or basted onto the fabric. It offers more flexibility as it comes in different weights and can be used for various fabric types. Lighter non-fusible interfacing provides minimal stiffness, while heavier options provide more structure.

For lightweight fabrics, such as silk or chiffon, lightweight or sheer interfacing is recommended to maintain their drape and softness. Medium-weight interfacing is suitable for medium-weight fabrics like cotton or linen, offering a balance between structure and flexibility. Heavyweight interfacing is used for fabrics like wool or denim, providing the most support and added stiffness.

It’s essential to choose the appropriate interfacing weight based on the fabric type and desired outcome of the project. Testing different interfacing options on fabric scraps can help determine the best choice for achieving the desired level of stiffness.


The weight of the fabric, the desired level of structure and support, and the type of sewing machine being used all play a role in determining the appropriate interfacing weight. However, one thing is certain – the quality of the thread used is essential for ensuring long-lasting and durable results. With it’s 100% core-spun polyester construction, this thread is guaranteed to withstand frequent washes and strain, making it an excellent choice for any sewing project.
