Ya, I bought some from the exact same place probably 5? years ago. Took a crapton of light behind it to do the transparency, but it worked.I am years too late for this thread, but I am looking for the same thing right now. I have found this place: mirrorsheeting.com and have ordered from them before, years ago, but I could have sworn that what we bought was much wider than 28-1/2" I'm sure it came in 54" before. Bummer, too, because I need 36" wide at the least. Gonna check out some of these links others put up in this thread.
