LoveCraftsman sez, "How to make a realistic corpse out of a cheap plastic skeleton in one hour."
Having experienced the tedium of creating a corpse with liquid latex and cotton fiber first hand I found this tutorial extremely helpful. It uses a cheap plastic skeleton, plastic dropcloths, and a heat gun to produce a surprisingly realistic final product. The one in the tutorial took about an hour and looks pretty good, particularly when compared to the latex treatments that take days to finish.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
