It is important to mix the plaster in small batches, it dries very quickly. With this in mind, it is best to start with about 1/2 C. of plaster and about 1T. fine sand.
Pour the plaster and sand into a container, anything that is disposable will do. We used an ice cream bucket. Slowly add cold water. Mix it to the consistency of a thin frosting.
We discovered if the water was warm or even room temperature the plaster hardened quicker. Once it hardens it’s impossible to work with and it had to be thrown out.
To keep the water cool, we just added ice cubes to the water container. This worked perfectly.
Another note: We used “Perfect Plaster” for our projects, because we had leftovers from a scouting project. If you have plaster of paris, that will work as well. Any crafting plaster will work.
What a great diy project with fabulous results.
Thank you Debbee, it was so fun to do. Are you going to try this technique?
