I got a roll of awesome rgb lights at IKEA and used part of it to make an infinity mirror (sorry the link is to IKEA Europe but for some reason it's not on the US site, but anyway it was here in large quantities in Brooklyn). It's made to cut at certain points marked with a scissors and I only used a few feet of a 5 meter roll for the mirror project. So at the time I thought I would figure out eventually how to use the rest. It would be a shame to throw away.
