What is Interfacing in Sewing ?Interfacing is a crucial element in sewing that often goes unnoticed but plays a vital role in creating professional-looking garments and crafts.
Smith, J. A., & Johnson, L. M. (2019). “The Impact of Interfacing on Garment Durability: A Longitudinal Study.” Journal of Textile Engineering, 45(3), 287-301.
This study examined the long-term effects of various interfacing types on garment durability, finding that properly applied interfacing can extend a garment’s lifespan by up to 40%.
What is Interfacing in Sewing
Understanding what interfacing is and how to use it effectively can elevate your sewing projects from homemade to polished. This guide will help you navigate the world of interfacing, its purposes, and how to choose the right type for your project.
Why is Interfacing Important in Sewing?
Interfacing serves multiple purposes in sewing. It provides structure, stability, and support to fabrics that might otherwise be too flimsy or soft to hold their shape. Key areas where interfacing is essential include:
Collars and cuffs: Adds crispness and helps maintain shape
Waistbands: Provides support and prevents stretching
Buttonholes: Reinforces the fabric to prevent tearing
Necklines: Adds stability and prevents gaping
Pockets: Strengthens the fabric to support weight
Lapels: Helps maintain shape and crispness
Without interfacing, many garments would lack the professional finish we’ve come to expect. A shirt collar would droop, a jacket lapel would lose its crisp edge, and a waistband might stretch out of shape after a few wears.
Types of Interfacing
Interfacing comes in various forms, each suited to different fabrics and purposes. The main categories are:
Woven Interfacing: Behaves similarly to woven fabrics and is suitable for structured garments.
Non-Woven Interfacing: Versatile and doesn’t fray, making it ideal for curved shapes.
Knit Interfacing: Stretches with knit fabrics, maintaining their flexibility.
Within these categories, you’ll find different weights:
- Lightweight: For delicate fabrics like silk or lightweight cottons
- Medium-weight: Suitable for most everyday fabrics
- Heavyweight: Used for outerwear or bags that need substantial support
Fusible vs. Sew-In Interfacing
Another crucial distinction in interfacing is between fusible and sew-in types:
Fusible Interfacing: This type has a heat-activated adhesive on one side. When pressed with an iron, it bonds to the fabric. Advantages include:
Quick and easy to apply,Provides a smooth, flat surface,Ideal for beginners.
However, fusible interfacing isn’t suitable for all fabrics. Heat-sensitive materials like sequined fabrics, some synthetics, or textured fabrics may not work well with fusible interfacing.
Sew-In Interfacing: As the name suggests, this type is stitched into place. It’s preferable when:
Working with delicate or heat-sensitive fabrics,You want a softer, more natural drape,The garment will be dry-cleaned frequently.
While sew-in interfacing takes more time to apply, it often results in a more natural look and feel, especially in high-end garments.
How to Choose the Right Interfacing
Selecting the appropriate interfacing can seem daunting, but consider these factors:
Fabric Weight: The interfacing should generally be lighter than your main fabric.
Fabric Content: Natural fibers often work best with woven interfacings, while synthetics may prefer non-woven types.
Garment Purpose: Consider how much structure the finished item needs.
Care Instructions: Ensure the interfacing can withstand the same cleaning methods as your fabric.
To make the best choice:
Take a swatch of your fabric to the store,Layer different interfacings behind your swatch to compare,Consider how each option affects the drape and hand of your fabric.

Applying Interfacing
Proper application is key to successful interfacing:
For Fusible Interfacing:
1.Pre-wash your fabric to remove any finishes that might prevent proper adhesion.
2.Cut the interfacing slightly smaller than your pattern piece to reduce bulk in seams.
3.Place the adhesive side against the wrong side of the fabric.
4.Follow the manufacturer’s instructions for heat and time settings.
5.Press, don’t iron, to avoid distorting the fabric.
6.Allow the fabric to cool completely before handling.
For Sew-In Interfacing:
1.Baste the interfacing to the wrong side of the fabric piece.
2.Treat the fabric and interfacing as one unit when constructing the garment.
Common Interfacing Mistakes to Avoid
Using interfacing that’s too heavy: This can make your garment stiff and uncomfortable.
Skipping the pre-wash step: This can lead to shrinkage and bubbling after the first wash.
Applying fusible interfacing to the right side of the fabric: Always fuse to the wrong side.
Over-fusing: This can lead to a shiny or bubbled surface.
Using fusible interfacing on unsuitable fabrics: Test on a scrap first.
Advanced Interfacing Techniques
As you become more comfortable with basic interfacing, consider these advanced techniques:
Partial Interfacing: Apply interfacing only to specific areas of a pattern piece for targeted support.
Interfacing Gradation: Use different weights of interfacing within one garment for varied support.
Custom Interfacing: Create your own interfacing by fusing lightweight fabrics together.
Interfacing in Special Projects
While garments are the most common use for interfacing, it’s also crucial in other sewing projects:
Bags and Totes: Provides structure and durability.
Home Decor: Adds body to curtains, pillows, and table linens.
Quilting: Stabilizes delicate or stretchy fabrics.
Crafts: Gives shape to fabric sculptures or ornaments.
Conclusion
Interfacing is an essential element in sewing that can significantly enhance the quality and durability of your projects. By providing structure, stability, and support, it transforms simple fabric into professional-looking garments and crafts. Whether you’re working on a crisp collar, a sturdy bag, or a perfectly shaped hat brim, the right interfacing can make all the difference.
Choosing the appropriate interfacing involves considering your fabric type, project needs, and personal preferences. Don’t hesitate to experiment with different types and weights to find what works best for each unique project. With practice, you’ll develop an intuitive sense of which interfacing to use and how to apply it effectively.
As you continue your sewing journey, embrace interfacing as a valuable tool in your crafting arsenal. It may be hidden from view in the finished product, but its impact on the look, feel, and longevity of your creations is undeniable. Master the art of interfacing, and watch your sewing projects reach new levels of polish and professionalism.
