Facings are separate pieces used to finish raw edges of a garment. They can be used to complete openings, finish scalloped edges, or neaten necklines. Common locations for facings include necklines, armholes, fronts and backs of garments, sleeve edges, and sometimes waistlines. There are three main types of facings: shaped, extended, and bias. Guidelines are provided for attaching facings properly in garments. Tips include cutting facings slightly smaller than the garment, altering patterns as needed, interfacing areas with buttonholes, and finishing edges without adding bulk or puckering.
