  1. 1

    Attach the four 9-inch by 4-inch by 1-inch wood planks together at their corners with a butt joint. Use a small line of wood glue when screwing into place. You should now have a wood frame.

  2. 2

    Make the bottom side of your wood frame. Drill a medium-sized hole in the centre of the bottom side. Thread the cord of the lamp kit though the hole and attach the light socket to the inside of the frame. Finish this by attaching four rubber feet to the bottom outside of the frame.

  3. 3

    Clean the sheet of Plexiglas with warm soapy water to remove any dirt and oils on the surface. Using a pencil, mark out the lettering or image for the sign on the surface of the Plexiglas. Paint in the design using your lettering brush and your choices of oil-based exterior enamel paint colours. Allow this to dry completely before moving forward. Fill in the areas not painted with two layers of black oil-based exterior enamel paint. Allow the paint to dry between each layer.

  4. 4

    Attach the back of your sign to a sheet of Plexiglas. With the sign side facing you, attach the Plexiglas to what will now be the front side of the wood frame. Use one screw for each of the four corners.

  5. 5

    Flip the frame over so the sign is now facing down. Install a low volt light in the lamp kit socket.

  6. 6

    Attach the flat wood sheet to the back of the wood frame. Use one screw to attach the top of the sheet to the top of the wood frame. This will allow for the back wood sheet to slide open, so you can change out light bulbs when needed.

  7. 7

    Stand the sign up onto the rubber feet. Plug in the light cord and turn it on to test the backlight for the sign.
