In sewing, elastic is a notion which is sold in narrow strips and generally serves to increase the ability of garment to stretch, either to accommodate movement or to make the garment suitable for wearers of many different physical sizes. Elastic comes in four forms of construction, each with costs and benefits. The component which performs the actual stretching is made of either rubber or a synthetic material such as spandex; this stretching component is then covered with polyester, cotton, nylon, or a combination of these or other fibers which allow it to be attached to clothing. High-quality elastic is able to be stretched to twice its original length and then return to its unflexed state without showing appreciable wear.^[1]
