I have to admit when you said it relies on body heat to smooth the lines (because you don't have a heat gun in the studio) I quite imagined someone hugging the clay form...and how odd would that look in a Kodak moment? LOL
Edited: Hugging AND sniffing the clay form. lol
Now that you mention it, it would be pretty bizzare, and in itself would be an analogy of caring for a child, since you try to build them up so that they can live up to their potential :p
