Last weekend I received a belated birthday present from my cousin. This is certainly not an item that I would normally purchase for myself but would be happy to find them in a deleted item bin or at a deep discount sale. I immediately thought that these would make a perfect Martian terrain piece for Space 1889 as a Sacred Grove.
The bases were covered with Liquitex Resin Sand, that included a paint mix of roughly 1 part red to 4 parts Raw Sienna. I then lightly sprinkled on some brown/red ballast, which I think was a Woodland Scenics product. After drying overnight I painted over the soil with a watered down GW dark flesh.
