just thought i would share--back from my local "big lots" and they have photo canvas for printers for $3 for a pack of five sheets of canvas. a pretty good buy! also lots of colored duct tape.
if you happen to live near a store and that interests you, i would hate to have anyone miss out. of course, i can only say for sure that the mission street big lots in san francisco has this stuff, but i think it's a chain store that tends to have similar merchandise in all their locations.
