We live on Oregon Avenue and on the phone I have to spell it for many people. That's where the idea originated. I found a font I like and blew it up then printed it out. Taped it down on styrofoam and used a razor blade from utility knife to cut a 45 ish degrees angle. Then removed the cut portion. Painted with latex then shot grey primer then thin black craft paint in lettering.
Looks pretty good to me! I recently did my first letting from printout and used 8.5 x 11 adhesive labels to print on. Worked ok on bead foam, but pulled up some beads when removing. Worked AWESOME on pink and blue foam board. Much easier than taping it down, tracing then cutting, Just cut to start with, then pick off the label.
