Fosshape ® makes for an excellent blocking material alternative to buckram. It is recommended that Fosshape ® is blocked or stretched over a mould/block first prior to applying heat. Once the desired shape is acquired, heat can be applied directly to the surface to create a more rigid form/shape (see below for heating instructions). Please note this material shrinks into its rigid form upon activation, so remember to allow for this in your design.
Heating is recommended using either industrial hot air guns, garment steamers or conventional steam irons. Overheating may cause holes/voids in the material and may eventually result in it burning. It should also be noted that this material will shrink upon heating and that re-heating it will not restore its original condition. For safety reasons, avoid bare skin contact with Fosshape ® while applying heat.
This product consists of breathable composite synthetic polyester fibre which is non-woven and features the relatively low melting point of approximately 93 degrees Celcius. When heated above this point, Fosshape ® becomes activated (sets in rigid form) and like all thermoplastics, will retain its molded shape once cooled. It is water and mildew resistant meaning that any application of water will NOT result in loss of structure or integrity and it results in none of the mess associated with other molding materials such as buckram and paper-mache.

We try our best to ensure colour consistency but cannot guarantee that two different products with the same colour description will have the same colour.
