Now off to gather supplies - - first up, foam board for the picture. Where do you get one that big?? Home Depot/Lowes - yep, it's the big foam pieces used to insulate houses. And it's cheap - $ 11 for the whole board and you can get a couple of pictures out of it. Then head off to the office store and ask for "the biggest engineer's print you can make" and hand over your jump drive. It is 4 feet by 3 feet and it was about $ 8.
