I wanted to try a different technique to create the Rock. I cut smaller shapes from the larger Rock shape then I painted the reverse side of a piece and quickly laid the piece on the surface and lightly tapped it down then pulled it off before it could dry. I added more paint to the pulled off piece and laid it back down. This gave me a mottled and uneven texture. The paint is a blend of gray blue, white, and a little black acrylic paint.
