RFID Shielding Pouch Out of 'Trash'

Step 6 Fuse aluminum can pieces into squares of plastic

Lining the pockets with aluminum can pieces allows your cards to remain shielded while the pouch is open. Each can piece is fused between #3 layers of clear and #3 layers black squares.

a. Lay down #3 layers of clear 8x8 (20.5x20.5) squares. Whichever side of the can you wish to have visible, place face down upon #3 layers of clear plastic. Center can piece in the square, a good 1" (2.5cm) from the top. Fuse. Repeat for the other three pieces.

When I ironed my can pieces, I found that the clear plastic shrinks more than the black and if I ironed the face of the cans too much it puckered and curled. Rubbing the 'heat sink' on top of the parchment to cool and flatten was very helpful. (Don't have a thick piece of sheet metal? Use the bottom of a frying pan.) Spend more time with the iron on the perimeter of the can pieces and keep the iron on top of the can pieces only long enough to fuse it. If you mess up, cut the can piece out of the plastic and do over. The plastic does not adhere to the aluminum.

*Optional: use only black bags and have the cans invisible. I liked the cans showing and it is MUCH easier to see them when you're sewing the pockets.
