How to use acetate paper on plaster

Start by dunking the plaster strips in the cup of water, and smooth with your fingers to activate the plaster.

Place the plaster strips on the paper, place a few down, one for each media. Also add folds to some strips for texture.

After the strips are dried on the piece of paper, start applying the first media to a strip of your choice. Use different colors, and different amounts.

Repeat for each media type.

Apply the medium onto acetate paper, and you can mix and match which acetate goes on which plaster strip to create different effects.
