I went to a couple of fire stations around and took pictures of things that looked like letters. I also did the same thing on a farm. Here is my first attempt at framing some of the letters, well matting them. I still need to buy the frame. The matte came as a double white set. I really wanted black so I spray painted the top one black with my chalk board paint. I might write out the rest of the verse along the bottom with white chalk.
Love the LORD your God with all your heart and with all your soul and with all your strength.
