What you'll need. A Skeleton Clear Plastic Tarps Variable Temperature Heat Gun (I assume it's possible to do this with an embossing heat gun, but don't. Get a proper one.) Wood Stain Brushes (I used both sponge and bristle brushes)
Sounds exactly like what it is. Wrap a layer or two of plastic around your skeleton. Then get ready to hit it with that heat gun.
Update: This project was inspired by Allen Hopps who showed us how to make human pelts out of trash bags. I thought, 'I wonder if drop cloths would work on skellies,' and they did! (I did find out later that Allen also had that idea...)
