Last year, I created a small industrial light box and I wanted a larger one ever since. I finally got around to making one! I used removable vinyl so I could change the art out as I wanted. But, I love this heart, so it just might stay!
Scissors (to cut vinyl)
Remove glass from frame and spray paint with frosted glass. I used two coats.
Drill a hole into the shadow box to fit LED cord plug in through.
The LED strips from Amazon are very long, just cut as needed for the size frame you use. (your first cut will have the plug part, if you wish to make additional light boxes, you will need to solder new power cords to the light strip)
Remove adhesive backing and line the inside of the box.
Cut your removable vinyl shape and place on top of glass.
