What is Interfacing?

Interfacing is a crucial textile material that reinforces and stabilizes fabrics in sewing projects. It’s often an unseen hero, supporting various garments and accessories. Essentially, interfacing is like a hidden layer between the outer fabric pieces, ensuring they maintain their shape and structure.

Types of Interfacing

Several types of interfacing are available, each designed for specific fabrics and applications. Here are the most common ones:

1. Fusible Interfacing

Fusible interfacing is the most popular type among sewers due to its ease of use. It has an adhesive side that bonds to the fabric when heat and pressure are applied, creating a permanent bond. Fusible interfacing is available in various weights, ranging from light to heavy, making it suitable for various projects.

2. Non-Fusible Interfacing

Non-fusible interfacing, or sew-in interfacing, does not have adhesive properties. Instead, it is stitched directly onto the fabric, providing stability without affecting the drape. This type of interfacing is ideal for delicate fabrics and areas that require precise control.

3. Knit Interfacing

Knit interfacing is specifically designed for use with stretchy or knit fabrics. Its inherent stretch allows the fabric to maintain its elasticity while providing the necessary support. It is commonly used in creating knit garments and activewear.

4. Woven Interfacing

Woven interfacing is made from tightly woven fibers and offers excellent stability and support. It works well with medium to heavyweight fabrics and is frequently used in constructing structured garments like blazers and coats.

5. Sheer Interfacing

As the name suggests, sheer interfacing is lightweight and translucent, making it perfect for delicate and sheer fabrics. It provides subtle reinforcement without adding bulk.

When to Use Interfacing?

Interfacing is used in various sewing scenarios to achieve different outcomes. Here are some common situations where interfacing prove invaluable:

1. Collars and Cuffs

Using interfacing in collars and cuffs of shirts or blouses helps them maintain their crisp shape and prevents them from becoming floppy over time.

2. Buttonholes and Button Bands

Interfacing reinforces areas where buttons and buttonholes are sewn, preventing the fabric from stretching or fraying around these essential closures.

3. Waistbands and Belts

Adding interfacing to waistbands and belts provides structure and stability, ensuring they don’t lose their shape during wear.

4. Bag Making

In bag making, interfacing is often used to add structure and strength to the bag’s body and handles.

5. Garment Fronts and Facings

Interfacing is applied to garment fronts and facings to maintain their shape and prevent them from wrinkling.

Tips for Using Interfacing

1. Choose the Right Type and Weight

Selecting the appropriate interfacing for your project is crucial. Consider the fabric type and weight, and match it with the corresponding interfacing type and weight.

2. Test on Scrap Fabric

Before applying interfacing to your main fabric, it must be tested on a scrap piece to ensure it adheres properly and doesn’t cause any undesirable effects.

3. Follow the Manufacturer’s Instructions

Different interfacing brands may have specific instructions for application. Always follow the manufacturer’s guidelines for best results.

4. Use a Press Cloth

When applying fusible interfacing, use a press cloth or a piece of scrap fabric between the interfacing and the iron to avoid any adhesive residue on your iron.

5. Interface Both Layers

Interface both layers separately for consistent support when working with two fabric layers, such as collars, cuffs, or facings.
