Unexpensive Faux Tin Ceiling tiles? I'm looking to make my relatives room with Copper look ceiling tiles...

I'm looking to make my relatives room with Copper look ceiling tiles (who can afford legitimate copper anyways?!). Any ideas what other stuff can we try ?
Answers:    Hi in attendance,
Just wanted to show you one of our closing summer's projects. We had duplicate target- to make the kitchen ceiling to look as close to real Copper as possible. We completed up installing PVC faux tin tiles. From my personal experience I can tell you that this is as close to the authentic Copper as it could be. And also consider that the installation is much simpler and faster than real tin - no preparation work required - of late paste some bonding agent and stick them up. So you save twice - on materials and on work , but at the end you enjoy fantastic ceilings.
Good Luck!!!
