This is a great essential for all design studios. Here we have a 4" Stiff Black Horsehair used to stiffen hem edges for a chic flare effect. This trim is a flexible type of netting made from polyester. With it you can stiffen and define straight and curved hems as well as add weight and body to any garment. Add a decorative touch to hats and costumes, perfect bridal gowns and other formal dresses, finish collars to shirts or jacket lapels, etc.
