Everything You Need to Know Before Choosing Interfacing

Interfacing is one of the most useful sewing supplies you'll ever own, yet it's also one of the most misunderstood.

If you've ever wondered why shirt collars stay crisp, tote bags hold their shape, or quilted fabric baskets stand upright, the answer is often interfacing.

Interfacing is a support material added to fabric to provide strength, structure, stability, or shape. Some types are permanently fused to the fabric with an iron, while others are sewn into the project.

The key is choosing the right interfacing for the fabric and project you're making.

What Does Interfacing Do?

Interfacing helps fabrics perform better by adding support where it's needed.

It can:

• Add body to lightweight fabrics
• Prevent stretching
• Help collars and cuffs keep their shape
• Strengthen waistbands and button plackets
• Give bags and purses structure
• Support home décor projects
• Improve the appearance and durability of finished projects

Without interfacing, many projects would feel soft, floppy, or lose their shape over time.

Common Sewing Projects That Use Interfacing

Interfacing is used in many different types of sewing projects, including:

• Shirts and blouses
• Jackets and coats
• Dresses
• Tote bags
• Handbags
• Fabric baskets
• Wallets
• Home décor
• Placemats
• Table runners
• Quilted organizers
• Appliqué projects
• Fabric postcards
• Memory projects

Many quilters also use interfacing when making structured bags, fabric boxes, landscape quilts, and appliqué designs.

Types of Interfacing

There are several different types of interfacing, each designed for specific fabrics and projects.

The most common categories include:

• Fusible Interfacing
• Sew-In Interfacing
• Woven Interfacing
• Non-Woven Interfacing
• Knit Interfacing
• Fusible Fleece
• Foam Stabilizers for Bags

We'll explore each of these in more detail in the guides that follow.

Choosing the Right Weight

One of the most common mistakes beginners make is selecting interfacing that's heavier than the fabric itself.

As a general rule:

• Lightweight fabrics need lightweight interfacing.
• Medium-weight fabrics pair best with medium-weight interfacing.
• Heavy fabrics require heavier support.

Matching the weight helps your finished project look natural while still providing the support you need.

Can Quilters Use Interfacing?

Absolutely.

Interfacing isn't just for garments.

Many quilting projects use interfacing to create:

• Appliqué
• Fabric collage
• Structured bags
• Wall hangings
• Fabric bins
• Decorative organizers
• Specialty quilting techniques

It's a valuable tool for adding shape and stability without adding unnecessary bulk.
