What is the function of interfacing in fabric construction?

• A. It adds color to the fabric.
• B. It makes the fabric heavier.
• C. It provides shape and stability to fabric areas such as collars, cuffs, and waistbands.
• D. It increases fabric weight uniformly.

Answer: (C)

Interfacing gives fabric areas extra body so that shapes like collars, cuffs, and waistbands stay crisp and hold their shape. It’s applied to the wrong side of the fabric (often with heat if it’s fusible) or sewn in, creating a stable layer that resists stretching and distortion. This stability helps edges press sharp and keeps the garment looking neat through wear. Different interfacing weights let you tailor stiffness: lighter for delicate fabrics, medium for most collars and cuffs, heavier for waistbands. It isn’t mainly about adding color or uniform weight; its purpose is to provide structure where the fabric would otherwise be too limp or weak.
