I love this idea, There was a way back when I was into ceramics that we used to do molds and that is by doing the acrylic resin is you made the molds(pep) a 16th of an inch bigger then the pull you want you can simply brush a little acrylic resin into the mold don't foget placement pins to make sure it lines up perfect the use mold release to poor you resin into the molds and boom you have your molds but that is just an idea.the pep molds once again is a great idea.
