The Original Tyvek Wallet

Step 8 Apply tape

Flip the envelope over again, address side down and fold it in half vertically, with the flaps still open to the sides. Open the small 1/2 in tabs and fold them out towards yourself. Make sure you fold the two layers together and crease them.

Apply double stick tape to the tabs on the side facing you. Now fold the tabs portion up towards the self-seal flap, sealing the double stick tape by pressing down hard to secure the tabs. This creates two credit card holders.
