My Son Made me a Light Table a few years back. It's wonderful. About 2 1/2 feet by just over 4 feet. He used 4 4ft florecent tube bulbs, a sheet of glass, put a white sheet of fabric down to keep out the glare and then another piece of glass. He even built a light switch and an electrical outlet into it. It's high enough to also use as a cutting table. I'm so blessed.
