Ferric Chloride (FeCl3) Etch Mask?

Hello,
I'm hoping to etch patterns into/through copper, nickel, and/or aluminum
foils using an aqueous solution of FeCl3. I was wondering if anybody has
any experience etching any metals with FeCl3, and which masks work for this
process. Any help would be greatly appreciated! Thanks,
Kevin
