Tulle, a lightweight, very fine, stiff netting, does not typically shrink. It is often made from a variety of fibers including silk, nylon, and rayon which are all resistant to shrinkage. However, it's crucial to handle tulle with care as it can easily tear, snag, or become misshapen. Although it doesn't shrink, tulle may contract or appear smaller if exposed to high heat. Therefore, it's recommended to avoid ironing tulle or exposing it to hot water. If you need to clean an item made of tulle, it's best to hand wash it gently in cool water and let it air dry.
