Tips and Suggestions

  • Due to the powder consistency of Plaster of Paris before adding water, mix out of reach of children. You might even consider using a face mask to prevent breathing in the powder.
  • I used both tempera and acrylic on plaster and they both work well. If it is a young toddler I'd recommend tempera since its easier to wash off.
  • Use a glitter paint to add sparkle or sprinkle on wet plaster or paris or paint.
  • For additional shine, an adult can spray acrylic onto finished project.

Silicone Mold Suggestions

    Some are seasonal and may be available only at certain times of the year. We really liked the durability of the Wilton silicone pans but there are many brands to choose from. Be sure to check the temperature rating and read reviews. Also be sure to check the measurements of each mold because it is difficult to tell the size just by the picture.
