Tulle and netting are 100% nylon and are meant to create the illusion of fullness. Tulle is a fine form of netting that comes in either 54 or 108 inch widths. It is primarily used for veils and to make skirts and dresses. It can also be used for decorations such as draping or tie backs on chairs. Netting comes in 72 inches in width. It's common use is in veils, primarily bird cage veils. Tulle's denier is 20 and netting's denier is 40. This means that the tulle is less dense than the netting. Even though the holes are smaller, the fabric is lighter overall.
