We carry multiple sizes of elastic trim, from ¼” all the way up to 1” wide, and they are available in both black and white. The length of the spool is variable and depends on the width that is ordered. Our Elastic Trim is made from both polyester fibers and rubber. This combination of materials creates a strong yet very stretchy and pliable elastic that has great tensile strength and elogational proportions. The materials have been knitted together to create a resilient material that will stand up to wear and tear. Our elastic is great for both home and professional sewing, tailors, seamstresses, DIY, crafters, garments, clothing, waistbands, sportswear, pants, skirts, and more. Can be used to make face mask straps. Our elastic trim is machine washable.
