The backside of my mountain is pretty much carved. Still a long way from finished but i think the bulk of the carving is finished. I have a pretty good pile of small pieces on the floor. I've seen some posts where this is used for talus but i have no idea how to do that since I can't just soak it all in a bucket of brown. The foam doesn't absorb liquid unless I'm missing something.
My question would be how do you color a large amount of small chunks of pink foam to simulate rocks?
