What Is Interfacing?
Interfacing is the hidden fabric sewn between the outer fabric and the lining. It gives shape to collars, cuffs, plackets, and waistbands. Learn the three weights and how to choose.
What you will learn
- Define interfacing and where it lives in a garment
- Distinguish fusible from sew-in interfacing
- Choose the right interfacing weight for a project
What interfacing is
Interfacing is a structural fabric sewn between the outer fabric and the lining. It gives shape to areas that need to stand up: collars, cuffs, plackets, waistbands, button placements. Without interfacing, a collar collapses; with it, the collar holds geometry.
Fusible vs sew-in
Fusible interfacing has heat-activated adhesive on one side. You press it onto the outer fabric and it bonds. Sew-in interfacing is sewn around the edges and floats inside the garment. Fusible is faster; sew-in is more durable and used in couture.
Three weights
Light interfacing: silk and lightweight cottons. Medium: typical shirting, blouses, dresses. Heavy: structured collars, waistbands, jackets, coats. Pick the weight one step lighter than the outer fabric so the interfacing supports without overwhelming.
