Fosshape 400® – Medium Weight, Heat-Activated Crafting & Cosplay Fabric (Black) (Sold by The Yard) (1, Half Yard)

Fosshape 400 is a unique, heat-activated fabric that transforms from a soft, pliable felt-like material into lightweight, gravity-defying shapes using a heat gun, iron, or steamer. Ideal for Cosplay, crafting, theater, and costume design, it’s the perfect solution for projects requiring flexibility, structure, and lightweight, comfortable support. Fosshape 400 can be easily cut with scissors, is paintable, and is resistant to fraying. Fosshape 400 offers a clean and professional finish on its own, but can be sewn with other fabrics, layered as a hidden stiffener, or it can be shaped into durable, stand-alone structures or art pieces. One of Fosshape’s standout features is its incredible shape memory: it springs back into shape even after being compressed. For example, a body form made from Fosshape can be folded into a suitcase and will bounce back with little to no deformation. Fosshape 400 is the medium weight and most versatile in the Fosshape family, making it ideal for interfacing and structural sewing. Available in Black and sold in yard lengths and sample sizes.
