What Is Featherweight Interfacing Used For?

When it comes to sewing, the right tools and materials can make all the difference. One such tool that often goes unnoticed but plays a crucial role in garment construction is featherweight interfacing. This makes it an ideal choice for creating professional-looking garments that are comfortable to wear. Whether you're a seasoned seamstress or a beginner, understanding the purpose and uses of featherweight interfacing can elevate your sewing projects to the next level.

How Do You Use Fusible Featherweight Interfacing?

When it comes to using fusible featherweight interfacing, there are a few steps and considerations to keep in mind. First, ensure that you choose the right type of interfacing for your project. Featherweight interfacing is a lightweight option that provides a subtle level of support and structure without adding bulk. It’s commonly used for lightweight fabrics such as silk, chiffon, and lightweight cottons.

To use fusible featherweight interfacing, start by prewashing and drying both your fabric and the interfacing to prevent shrinkage later on. Next, lay your fabric on the ironing board with the wrong side facing up. Then, place the interfacing adhesive-side down on top of the fabric, aligning the edges.

Using a press cloth or a thin piece of cotton fabric, cover the interfacing, and apply heat with an iron set to the appropriate temperature for your fabric. Press firmly and move the iron in a back-and-forth motion for about 10-15 seconds in each section, ensuring that the heat is evenly distributed.

Allow the fabric and interfacing to cool completely before handling or moving them. This will help the adhesive bond to the fabric properly. Once cooled, you can trim any excess interfacing if necessary.

When sewing with fabrics that have been interfaced, it’s important to choose the right thread for your project. One option is the Madeira Aerolock Premium Serger thread, a high-quality, core-spun thread made of 100% polyester. This thread is designed to withstand frequent washes and strain, making it perfect for use with sergers and coverlock machines like the Janome CoverPro family.

Tips for Choosing the Right Type and Weight of Interfacing for Different Fabrics

When it comes to choosing the right type and weight of interfacing for different fabrics, there are some important tips to keep in mind. First, consider the fabric you’re working with. If you’re using a lightweight fabric such as silk or chiffon, you’ll want to choose a featherweight interfacing. This type of interfacing is very thin and lightweight, allowing it to support and stabilize the fabric without adding bulk or stiffness.

On the other hand, if you’re working with a heavyweight fabric such as denim or canvas, you’ll need a heavier weight interfacing. This type of interfacing will provide more structure and stiffness to the fabric, helping it to maintain it’s shape.

It’s also important to consider the intended use of the garment or project. If you’re making a garment that needs to drape and flow, such as a dress or blouse, a lightweight interfacing will be suitable. However, if you’re making something that requires more structure, such as a jacket or bag, a heavier weight interfacing will be necessary.

Lastly, always follow the manufacturer’s instructions when it comes to choosing and applying interfacing. They’ll provide guidance on which type and weight of interfacing is best for the specific fabric you’re using.


It’s lightweight nature makes it ideal for use in lightweight garments, allowing them to maintain their fluidity and comfort. Additionally, it can be used in combination with other types of interfacing to create customized levels of support and reinforcement.
