Copper tape

copper tape !!!

any size any color

as long as it conducts.

Digikey [can help you out here. I used this stuff for the [Puzzlemation tray, and it works OK.

I say “OK” instead of “great” because it does tend to curl and come unstuck over time. If SFE tracks some down, maybe they can find something more permanent?](http://www.puzzlemation.com/)](Electronic Components and Parts Search | DigiKey Electronics)

Try a stained glass supplier. The copper tape used for stained glass has a very strong, pressure-sensitive adhesive.

Another source would be an outfit that sells parts for electric guitar making (such as Stewart Macdonald) - copper tape is used to shield control cavities. Sticks well (never had it lift) and the sticky side is conductive (which is useful if you have to overlap layers).

You can also get copper roofing flashing in rolls from Lowes or Home Depot. It’s too thin to make project boxes out of, but is great for shielding. It also has an adhesive on it.
