Fosshape 600 is heavier and thicker and thus designed for more rigorous use. Dimensions: 45" x 36", weight: 18oz./yd, 180" thick.

Fosshape 400 Black is a great option for top hats and other men's hats as it's already black. Dimensions: 45" x 36", weight: 18oz./yd, 180" thick.

Fosshape is a replacement for buckram fabric. Unlike buckram, which can fray, isn't water-resistant, and needs a separate stiffener to give it shape, Fosshape is heat-activated. 

Use it for reinforcement and stiffness, millinery, puppets, masks and props. It can be dyed to whatever color you need, or it can be layered with other fabrics -- or even painted. 

It effectively replaces buckram, paper mache and sculpted foam.
