This UNIQUE braided elastic roll is general purpose braided elastic for sewing casings on waistbands, sleeves, and necklines in garments. It includes one white roll measuring 6 mm wide by 200 m long, giving you a bulk supply for alterations, repairs, workshops, and production sewing. Braided elastic can narrow as it stretches, so keep it inside a casing and avoid stitching through to maintain even stretch.
