I got one of the slim LED light pads for my birthday and I love it. (Tattoo artists use them a lot.) I received the "A2" size which is 18" x 24" - large enough for just about anything you want to trace. (DH said is was around $100). The "A4" size is an 8" x 10" size and are available for under $50. Ebay and Amazon have quite a few to choose from. I highly recommend the LED boxes as they are thin and easy to use. I used to use my patio doors, then my bay window to trace. Now I use the LED pad.
