Facing

A piece of fabric that reproduces the shape of the edge of a garment (armhole, neckline, lapels of a collar etc). The facing is sewn to the edge concerned, then turned to the inside of the garment. The seam is thus invisible and the final edge is very neat. Using a facing is recommended for curved shapes, where making a regular hem is hard, and inside jackets and coats, since the inside is often visible when these garments are worn.
