Print the image or photograph to fit the surface using a laserjet toner printer. Remember to reverse any words so that they will read correctly.
Paint the surface with acrylic paint. Let dry completely.
Place your image on a mat with the ink side up. Squeeze a generous amount of Mod Podge Photo Transfer Medium onto the photo and spread with a foam brush.
Continue spreading the medium until it obscures the image. Be sure to get the corners well.
Lay the picture image side down onto the surface. Smooth down, removing any air bubbles. A brayer helps here, as does having a wet rag (see Notes section).
Set aside for 24 hours to dry.
Place a damp cloth down onto the back of the photo for several minutes. Start rubbing away the paper very, very gently. Rub harder as you get more comfortable, but use a light touch.
After removing the top layer of paper, let dry a little and then repeat. It's better to rub gently and repeat the wetting process several times than to rub too hard and rub the image away.
Once you're satisfied with the image, further distress the piece with sandpaper if you like. Add a coat of Mod Podge Matte (or two) on top and let dry.
