How It Works

Elastic should be cut shorter than the body measurement so it stretches to fit snugly. For waistbands, 75-85% of your waist measurement is typical. Braided elastic narrows when stretched (use for casings), knitted elastic retains width (most versatile), and woven elastic is firmest (good for waistbands in pants and skirts).
