Homebrew PCBs

I am currently trying to see if I can find some copper foil that I
could adhere to other materials such as glass. I am wondering how
difficult it would be to make PCBs that are just a bit different. If i
could adhere foil to a glass sheet that would be kinda cool. I suppose
the radio guys use ceramics? I am not sure how easy this is but i
would like to find out. 

Anyone worked with copper foils? Got any sources for getting hold of some?

Thanks
