Hmm, I'm thinking an easy way to do it might be to print off a copy of the design and trace it onto a piece of craft foam. Cut it out with an exacto and glue the design down to a flat surface. Spray that with some gloss primer if you want a nice smooth finish to it and then some crystal clear. Now do a plaster mold either with ultrcal or plaster of paris might be easier to find. Then remove the design from the mold and use the latex in that. The latex won't be quite as flexable as dragonskin but would still look good I think.
Hopefully this was helpful to you.
