I would imagine that if you really wanted to you could say that you have an eating disorder, because it's causing you not to eat, irrespective of whether the origins of the disorder are physical or mental. I myself would be more disposed not to call it an eating disorder because I wouldn't want to be considered to be in the mental state of those people with eating disorders of more typical origin.
Sooo...I remember a while back we talked briefly about casting rubber (I think), but we never made anything of it.
I'm insanely interested in it right now, as well as casting in resin. I know the general requirements, but it's the chemicals and all that stuff - really getting started, that I'd love some tutorial time on if you have the free time some day.
What I'd like to end up with is some custom-made Batman costume pieces for this Halloween.
I'm about at the point where I'm ready to buy a manikin chest and some sculpting putty.
