WonderFlex and Fosshape

Wonderflex is a malleable composite - like a thick plastic sheet - that you can cut and shape with heat from a steam iron or heat gun. it sticks to itself, so you can build out large costumes, or do intricate piecework to build masks and stages. It is like buckram but easier to use and flatter-more consistant surface for making body armor and helmets and such.

Fosshape is like a heat malleable felt that you can cut and pull and shape for hats, masks, giant but lightweight costumes and props. Steam iron works best. Milliners love this for awesome shaping - easier to use than buckram and lighter weight, so your fascinators float. It can meld to itself with heat, or you can glue, staple and sew it.

To make a breast plate: cover a dress form with tin foil. Protect your hand with an oven mitt, and hold the edge of Wonderflex near the shoulder. Apply heat from a super hot hair dryer or a heat gun from the hardware store. Work from the breast out - point heat at the nipple and begin to shape.

Pro-tip: lay dress form flat - work with gravity
Pro-tip: work in pairs - one holds, one heats
