Foamcore base. Plaster Bandages cover all foamcore.
When dry, 2 coats of plaster of paris were brushhes on. Sponge
painting with latex paint gave the illusion of marble structures
with the same technique to create the hundreds of patio stones.
I did 5 different textures on large sheets and then cut them
to 1 cm X 2 cm stones. Plastic Flowers from dollar store are
hot glue gunned to the plaster structures.
