For the entrance sign, I tried a different distressing technique. In my attempts to speed up the "stone" creation process
I carved the stones with a dremel from 2 inch pink foam board. I think attempted to melt the edges with the propane torch.
This didn't work well on its own, so I used sandpaper to mold the stone edges after the foam cooled. It created a much rougher
look than on the walls. Here are some pic's.
