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.
