1. Follow this Plaster of Paris Tutorial on Craftideas.info to make the castings. Then paint the snowmen in colors you wish. Though the plaster of Paris dries white, it is recommended to also paint the snowmen with white acrylic paint to get a good saturated color.
2. Then brush on glue onto the front sides of the snowmen.
3. While the glue is still wet, shake on the glitter and set aside to dry. Once dry, tap the snowman so that excess glitter falls off.
