Choose your letter and prepare if necessary.
Paint your letter in the color of your choice, using spray paint or brush on acrylic paint. Let dry.
Trace your letter onto your paper of choice. If the back and front sides are the same, trace the backside of the letter.
Carefully cut the paper, making sure it fits just right or just a little bit bigger.
Apply a layer of Mod Podge to the letter, then smooth down the paper. Once dry, apply two or more layers of Mod Podge.
To give the letter a vintage effect, mix some Mod Podge with a bit of brown paint. Paint on the letter sparingly. Wipe away excess.
Let dry completely before using.
