A paperbacked adhesive web that turns any fabric into a fusible fabric. The backing paper is often called "release paper.” It can be used to fuse fabric to fabric or to a porous surface such as wood or cardboard. It must be ironed to adhere it to fabric. You can also fuse other fibers to it, as well as apply other art materials like paint and foil. It has no grain so it can be cut and applied in any direction.
