Wallet made from Tyvek mailing envelope

Step 9 Center adhesive strip

Place one of the smaller strips inside, across the inside flaps on part B / C and onto A. This will form some divided inside pockets. Remember to place the adhesive strip slightly off center, so that when you fold the wallet, it does not fold on the adhesive strip.

You will be left with an extra strip of adhesive, use it to further customize your wallet or make repairs later on!
