A craft store near me was going out of business, and I found the rock molding kit from Scene O Rama for $1. There was enough plaster to make 2 molds of each rock. I painted them as instructed with the provided paints, glued them to balsa squares and rectangles, added some dirt and the talus. Some bushes added for color and interest. I wouldn’t use balsa wood for this again. The washes and thinned down glues caused the balsa to curl.
I figured id use them as difficult terrain indicators in our D&D games. I’m thinking about running the old timey Isle of Dread adventure for my group, maybe these will come in handy.
