I'm throwing a Superheroes/ villains themed party this year and in the backyard I'm decorating an area as the Lab for the character I'm portraying Dr. Pamela Isley, better known as Poison Ivy from Batman. I'm already growing lots of vines and I'll set up a desk with vials and jars...
My take on "Ruins" arm How to
cut arm and hand out of couch cushion foam
use coat hanger pieces to stick inside fingers so you can set them how you want
I also used a coat hanger wire thru wrist area to bend it
paint with with latex paint
do second coat with a slight skin tint
