I discovered some Casting Compound so will try again to create groping hands. I used medium sized rubber gloves last week to create some creepy hands.
This time, I'll use small gloves and I'll cup them in wet sand as they dry, back down, so that formation occurs without air bubbles and uneven spots.
Also, I think I'll lubricate the inside of the gloves with maybe an oil of some sort. I'll experiment and see what works.
