Can we explore this local biz?

Well, it's been around for years... and years... and years.

I haven't ever seen one. Speaking personally, it sounds like a hard sell -- of the folks I know here, I can't think of many who'd order one, even for a child's bedroom.

But... if I'd had the idea and was going to make a go of it, I would actually buy some flourescent stencil paint and some star stencils and set up my own bedroom ceiling or bedroom with this. See how hard it was to do, how long it took, and how I liked the results. If I liked them, I would invest a little money in color coordinating a section of my bedroom, PHOTOGRAPH the bedroom to show the stars and the decorating, and use that as a selling point for local installations.

Actually, what I'd do is promote it and sell kits for the homeowner to do it themselves.
