Spoon mixture into mould. Press mixture into mould with a sponge, removing all excess moisture. Continue process until mould is well packed and excess water is pressed out of paper. Place mould in microwave on high for 2 minutes. Remove from microwave and allow cooling, then, microwaving another two minutes.
Paper is done when paper releases from the sides of the mould.
Release paper cast by gently tapping mould on counter. Microwave your paper cast shape on a paper towel 5 more minutes or until dry. You may use any type of paper although you may need to alter the amount of stiffener you use. These make great ornaments also. Have children decorate with glitter, buttons, paints, markers, beads, etc.
