Would anyone out there who has done a paper circuits program with adhesive copper tape be willing to share where you found the tape at a decent price? Need it for about 300-500 person event. I'm seeing some for $2.95 a roll (1/4 in width, 50 feet) but it doesn't have conductive adhesive and is pretty thin (.08 mm thick) and am wondering if it will work well enough to light up a 5mm led powered by a cr2032 coin cell battery? I can't afford the over $10-20 dollars a roll I'm seeing on other sites.

Therefore, as opportunity offers, let us work for the good of all....
