Interfacing is a material used in sewing to add structure, stability, and strength to fabric. It is applied to areas that need extra reinforcement, such as collars, cuffs, waistbands, and buttonholes. Interfacing helps fabrics maintain their shape, prevents stretching, and improves the overall durability of a garment.
Types of Interfacing
There are different types of interfacing, each designed for specific sewing projects. The main categories include:
1. Fusible Interfacing
- Has a heat-activated adhesive on one side.
- Applied by ironing it onto fabric.
- Easy to use and commonly found in most sewing projects.
- Available in different weights (light, medium, heavy) depending on fabric type.
2. Sew-In Interfacing
- Does not have adhesive and must be sewn into the fabric.
- Ideal for delicate fabrics that cannot withstand the heat of ironing.
- Provides a softer, more flexible structure compared to fusible interfacing.
3. Woven vs. Non-Woven Interfacing
- Woven interfacing looks like fabric and has a weave pattern. It must be cut with the grain.
- Non-woven interfacing is made from compressed fibers, does not have a grain, and can be cut in any direction.
- Knit interfacing is a stretchable version, used for stretchy or knit fabrics.
When to Use Interfacing
Interfacing is essential in many sewing projects. It is used in:
- Collars and cuffs – Adds crispness to keep them structured.
- Buttonholes and plackets – Prevents fabric from stretching.
- Waistbands and belts – Provides strength and stability.
- Bags and purses – Helps maintain shape and structure.
- Appliqué and embroidery – Prevents fabric from puckering.
How to Apply Interfacing
For Fusible Interfacing:
- Cut the interfacing to match the fabric piece.
- Place the glue side (shiny side) against the wrong side of the fabric.
- Use an iron on the appropriate heat setting (without steam).
- Press firmly for a few seconds, ensuring the interfacing adheres completely.
- Allow it to cool before handling.
For Sew-In Interfacing:
- Cut the interfacing to the same size as the fabric.
- Pin or baste the interfacing to the wrong side of the fabric.
- Sew it in place, following the fabric’s seam allowances.
- Remove basting stitches if needed.
Choosing the Right Interfacing
- Lightweight fabrics (silk, chiffon) – Use lightweight interfacing to maintain drape.
- Medium-weight fabrics (cotton, linen) – Use medium interfacing for structure.
- Heavy fabrics (denim, wool) – Use heavy interfacing for durability.
- Stretch fabrics (jersey, knit) – Use knit interfacing best mini sewing machine to maintain flexibility.
Conclusion
Interfacing is an essential material in sewing that enhances fabric strength, structure, and durability. Whether using fusible or sew-in, woven or non-woven, choosing the right interfacing ensures a polished and professional finish to your sewing projects.
