I have several small plaster of paris face masks. They measure 4x3 inches. and are no longer available , as far as I know. Originally purchased at a Ben Franklin craft store several years ago they are very feminine looking and perfect for the designs that I have created. Are there any instructions for making my own mold using one of the masks I have and using a simple plaster of paris?
I think I found a tutorial for you: http://www.wikihow.com/Make-a-Latex-Mold
