Thanks Bellaboo!
I have been haunting my Walmart looking for the Crayola Light-up Tracing Pad and it was finally on the shelf at $25.96. More than what you paid for yours but I snapped mine up anyways because there were only 3. It takes 3 AA batteries and is really bright with the led lights. Here is a sample of a pattern under my really thick muslin with the lights on.
