Wonderflex, also known as Altraform, comes in a precut sheet 43" by 55" Both sides are covered in a thin muslin-one side a little heavier than the other. The heavier side will prevent the material from sticking to itself and other materials while the lightly covered side will allow the AltraForm to stick not only to itself but to other types of plastics as well with the application of dry heat. Decorate as with the other thermoplastics.
