This sampler package includes one half yard x 44" wide pieces of all three Fosshape® thicknesses: 300, 400 and 600. This easy to use thermoplastic is a great replacement for buckram. It is a steam activated felt like fabric that will not fray, binds to itself, and can be covered with fabrics to provide a rigid base. It is easy to use for blocking, without the sticky residues or drying time. It has multiple creative uses including millinery, masks, theater props, puppets, cosplay, sculptures and costuming. Please see photos for suggested tools for blocking Fosshape® on wooden hat blocks.
