Facing

In sewing and tailoring, facing is a small piece of fabric, separate or a part of the fabric itself, used to finish the fabric edges. Facing makes a garment look professionally finished with the seams well hidden inside the folds of the facing. Facing is mostly used to finish the edges in necklines, armholes, hems and openings. They are also used widely in all other sewings like quilts and home decor items like curtain hems.
