INTERFACING

Interfacing is an auxiliary material joined (most often fused with a hot iron) to the wrong side of fabric to give certain areas of a garment firmness, volume and stability of shape. Interfacing is the 'invisible frame' of clothing: it is thanks to it that collars, cuffs, jacket fronts, plackets, belts and waistbands hold their shape. Without interfacing these details would be soft and shapeless. Interfacing comes in fusible and non-fusible kinds, of various weights — from the finest for light fabrics to stiff for headwear. A properly interfaced detail looks crisp and holds its shape for a long time. Interfacing is a hidden construction foundation, in which an auxiliary material gives the details of a garment firmness and stability of shape, being the invisible frame on which the crispness of a collar, front and the whole silhouette depends.
