Print and glue text: I printed the outlined text on my printer, then I glued it with liquid silicone to a thin piece of corkboard. I printed a mirror image so the side exposed would be the right one I pressed it with an iron (turned off) to keep the corkboard (which comes in rolls) from curling while the glue dries. Using a very sharp scalpel, I cut out the letters as close to the original printout as possible.
Paint background: I used two different shades of grey acrylic paint to paint the board, and make it look like the top, darker paint was old and faded. When going over the gray I kept the brush very dry to leave random areas unexposed.I then used ocher and a dark red to paint some “stains” on the board. This is totally free-style. There’s really no right way to go about it.
Paint letters: I painted the letters white with acrylic paint. I gave it two coats, letting them dry in between and after.
Aging the letters: I used a filter full of coffee grinds with all the liquid squeezed out and used to age the letters.
Glueing the letters: I then glued the letters onto the background using
Placing on the wall: I used double-sided tape to place over the bathroom door.
