Back Lit signs can be made with a printer and overhead projector film. First you need to make your sign in the correct size to print and make it. This was made with a greeting card program and measures a shade under 3 by 2 inches. Smaller than this and they get too hard for my fat fingers. Also cut out a piece of white plastic (.030 or so) a piece of foamcore. Cut the foamcore as shown.
