With lights installed, cut strips of duct tape in the color of your choice. I use black or brown since I have that on hand. This makes a "picture fra...
Having made some of these earlier, I decided to add a few more for the Christmas season. These light boxes, or signs are easy to make, very low cost (the only thing I have to buy is the lights). Lights used are mini-incandescent lamps that are low watt, low heat regular Christmas lights. If purchased at the end of the season, strings can be had for as low as $1.00 each! No "wiring" is required, just use the lamp strings as purchased. Be aware, that these lights should not be left on unattended.
Step 1: First Cut Acrylic or Glass For The Front of the Sign
I have a lot of picture frame acrylic and glass that is no longer used for pictures, so I use this instead of buying some new material. To cut acrylic, a special tool is available, but can be cut by scoring with a craft knife or box cutter and snapping on the line. For glass, a glass cutter is needed.
Step 2: Decide On Message For Signs
I chose "Noel, and Blue Christmas" for these two lightboxes. They are printed out on regular bond in the font and point size selected. Next, I glue the words to a piece of cardstock. Then, the letters or words are cut out as though it were a stencil. These words are then glued to the piece of acrylic or glass faceplate.
Step 3: Make Boxes For Signs
To make the boxes, I use the faceplate as a pattern, and out line that on a piece of regular corrugatged cardboard. Then, for the sides of the box, I add about 1 and 1/4 to 2 inches for each side. Cut out as shown, fold sides up and tape into place. I add a one half inch strip of cut cardboard to the inside top edges for support for the faceplate.
