As far as that glass goes, don't bother with contact paper...sandblasted glass or acid etched glass is not that expensive. I buy clear 1/8 inch thick glass for 75 cents per square foot, sandblasted is 92 cents and acid etched is 1.20 dollars. Depending on size you would have to get something thicker and that can up the costs quite a bit, so my question is how big would this be? Tell me that and I can tell you an estimate for the retail price. As an aside I use 1/4 inch thick glass on my painting table (4 feet by 8 feet) for painting up church windows and I hang 8 lights below it to throw light up onto my drawing, put the glass on top then paint the tracing lines. I would recommend the acid etch since sandblast tends to leave fingerprints.
