Copper foil


I just recently started a DIY project and wanted to know if anyone knows of a copper foil distributor or manufacturer. I am looking for .0075 thickness which is hard to find. Also, if you have info using the copper foil I am curious how you are using it in your system.

Thanks

Foil conductors. Anyone know of a designer who builds silver or copper foil for IC's?
Nordost, Goertz, Mapleshade, Allen Wright/VSE are a few. McMaster-Carr sells raw electronics-grade copper and there are several small distributors of silver foil.
From what I undertand "foils" might be easier to use in speaker cable designs than in interconnect designs.
