The body is sculpted in Chavant clay, which I struggled to make smooth using just my fingers. I also tried water and a cotton bud, with little success. There's probably a solution-solution, but I'm cautious of causing a chemical imbalance that might upset the silicone curability.
He currently stands at 6" tall, exactly. Probably another 2" when the head is attached. Though when cast and complete, he'll slouch in a goblin like pose, reducing him back to around the 6" mark.
