What is a key consideration when selecting interfacing for a garment?

Answer Details

Interfacing is a textile material applied to specific areas of a garment - such as collars, cuffs, waistbands, and button plackets - to add structure, body, and support. It prevents these areas from stretching, sagging, or losing their shape during wear and laundering.

The key consideration when selecting interfacing is fabric weight and stability. The interfacing must match the weight and drape of the outer fabric. A heavy interfacing on a lightweight fabric will make the garment stiff and unnatural, while a light interfacing on a heavy fabric will fail to provide adequate support. The goal is to reinforce the fabric without altering its intended drape and appearance.

Stretchiness is relevant only in specialised cases, such as knit interfacing for stretch fabrics, but it is not the primary selection criterion. Decorative texture is not a function of interfacing since it sits between layers and is invisible in the finished garment. Colour matching is a minor consideration - interfacing is hidden inside the garment and is typically available in white, black, and grey to avoid show-through, but this is secondary to achieving the correct weight and stability match.
