Michael,
I did it by photo copying a design onto rice paper. Word of caution, test the inks first as some will bleed. I had this happen to one of mine while appling it the wife came out to talk with me and I dabbed on too much epoxy while talking and that one weeped around the edges while the others didn't. Also try it on a test panel with it standing up to see if it will run. What worked flat might not work on the side of the hull.
