Using Super Sculpey polymer clay in these molds I was able to create multiples of the carvings I would need to adorn the altar.
Starting at the top of the altar I applied a veneer of Apoxie Sculpt clay.
I textured it to match the stone work I had done on the Skull Island wall.
When I was finished I carefully pressed the baked Super Sculpey carvings into the wet Apoxie Sculpt clay. When the clay had cured I moved on to the next tier of the altar.
