hi everyone. still kinda new here, sorry if i posted this in the wrong place... but, i'm JUST getting into making superhero costumes and learning as i go. right now, i'm preparing to do a Gotham City theme, and i need to know how to mould and cast Robin and Riddler masks and things as such. i know how to sculpt the mask, and i have dragon skin 30 to make the mask. but how do i get the mould? from what i can gather, i make a clay dam around the mask, fill with plaster, and then pull it off? this is the part i'm confused about. i can't seem to find the answer anywhere!! yeah. between the sculpt and the pouring of dragon skin 30 into the mould is where everything is fuzzy. is there anywhere that i can find a detailed step by step? or does something like that even exist?
