Often called the “buckram replacement”, this unique felt-like fabric (45″ wide or 114.3 cm x 1yrd length) is heat activated to achieve rigidity, stiffness and surface enhancement without the use of water, messy or hazardous additives. Synthetic FOSSHAPE® 300 can easily be cut with scissors, will not fray like conventional woven fabrics and can be readily sewn to itself or other fabrics as a hidden stiffener or shaped into stand alone structures. Mildew resistant and dye-able as well. Fabric steamers are the often preferred method for forming a desired amount of rigidity and stiffness, but conventional steam irons or an industrial hot air gun may oftentimes be helpful. The level of stiffness is achieved by adjusting heat, time and pressure. Applications include: costuming, lightweight crafted reinforcement, theater props and set design, craft-work, puppetry, millinery headpieces, masks, sculptures, museum mount making and more.
