Elastic Trim is ideal for adding stretch to a variety of garments. Elastic trim describes any trim that features a piece of rubber or elastane surrounded by woven fibers like cotton or polyester. Elastic can stretch up to twice its length. Elastane was invented in 1958, and in 1962 it revolutionized the clothing industry. Although rubber might seem like a modern invention, it has been used by humans for thousands of years. Utilize elastic trim to create ruffles on the sleeves of a blouse, or a waistband on a circle skirt.
