We shaped and hacked-up a lot of cheap urethane mannequins for Fosshape use. I'm afraid I never had the time to focus on it in the way Jim was able with this example. I have wished for a robust version of an old adjustable dressmaker's form that would allow you to tailor the size if the figure, and then collapse it from the inside so you could remove it from the fused Fosshape form. Sadly, I've never found one that would withstand the pressure that the shrinking Fosshape can exert.
