Types of Sewing Interfacing and Their Uses
Sewing interfacing is a material used to add structure, support, and stability to fabric in garments and craft projects. There are several types of interfacing, each suited for different fabrics and purposes. Choosing the right one ensures a professional finish and proper shape retention in your project.
1. Fusible Interfacing Use: Most common type, with a heat-activated adhesive on one side. Best for: Collars, cuffs, waistbands, button plackets, bags, and quilting. Suitable fabrics: Woven or knit fabrics that can withstand heat and pressure. Keywords: fusible interfacing, iron-on interfacing, easy-to-use interfacing
2. Sew-In (Non-Fusible) Interfacing Use: Sewn into the garment instead of fused; preferred for delicate or heat-sensitive fabrics. Best for: Formalwear, silk garments, lightweight fabrics, and when more control is needed. Keywords: sew-in interfacing, non-fusible interfacing, interfacing for delicate fabric
3. Woven Interfacing Use: Has a grain line and behaves like fabric, providing soft structure. Best for: Woven fabrics, tailored garments, and professional finishes. Keywords: woven interfacing, structured interfacing, interfacing for shirts
4. Non-Woven Interfacing Use: Made from bonded fibers with no grain; can be cut in any direction. Best for: Casual garments, craft projects, and general reinforcement. Keywords: non-woven interfacing, easy cut interfacing, interfacing for bags
5. Knit Interfacing (Tricot) Use: Flexible and stretchy; maintains stretch in knit garments. Best for: T-shirts, dresses, activewear, and stretch fabrics. Keywords: knit interfacing, stretch interfacing, tricot interfacing for knits
6. Heavyweight / Extra-Firm Interfacing Use: Adds firmness and rigidity. Best for: Tote bags, hats, belts, crafts, and structured collars or waistbands.
Interfacing is available in black or white, and in multiple weights — always match the weight of the interfacing to the weight of your fabric for best results.
