Dear Advisers, I know there was a thread on moulage and flexwax, but the archives only goes up to June 03. I want to cast my 8th graders hands in plaster. Using a box and mould to make a relief, like a plaque with the palm of their hand 3-D. I thought I could use my Roma Plas. clay but it is too hard. I want something reusable as I have to do 30+ Any help or guidance you can give me is appreciated. I am looking at flexwax and moulage in the Sax catalog. Happy Halloween. Thanks Carol
