Default Passive EMI shielding?

Hello, If I had a small circuit I would like to shield from EMI, what could I use to do this? I don;t want some $100 solution. Thx for the info guys.

if you need a small shielded box, you could make it out of unetched pc board material, and solder the edges together....

Somebody was telling me that anti-static bag-the type you get components and PC cards in would work but I am not sure. Any opinions on that?
