I'm in the works of improving my ceilings. I have an indoor haunt in a mall, and currently my ceilings are those white 2ftx2ft tiles that look like an office. While I can't build a ceiling on top of my walls because that would block the sprinkler system, I can put a thin layering on the current white tiles. That said, I'm considering something like this: (and painting them myself), but they are not as haunted as I would like them to be. Does anyone know of vendors of ceiling facades or ceiling tiles that can be used for a haunt? (aka creepy ceiling facades or creepy ceiling tiles).
