This is 3/4" non-roll knit elastic sold by the yard, vs pre-packaged, so you buy only the amount you need.

Knit elastic has a smooth appearance and is soft against the skin. Knit elastic does not become more narrow as it stretches and does not lose resiliency when sewn. Knit elastic can be used for many purposes and is best for lightweight and medium-weight fabrics.

Machine washable/dryable in temperatures up to 200F.

Made in China.
