RFID BLOCKING, MADE SIMPLE Answered

I have seen RFID wallets, sleeves, and cards.  I like the IDEA of RFID blocking cards that you sandwich your credit cards between.
So, my question is thus...
If I had two cards made of 21 gauge aluminum and placed them on in the last pocket on both sides of my wallet, would this block the RFID scanners?  If not, then what would it take?
What just programming some RFID chips and put them in my wallet to eff with the scanners?  I know there are things like this in the market, but very over priced.  I have contacts in the RFID scanning and deployment world, so it would not be hard for my to get my hands on this stuff.

What do you all think!?
