I have made a very lightweight but functional wallet / art piece, from a Tyvek postal envelope. Inspired by the duck tape wallet, I thought I would like something a little lighter in weight. What better material than tyvek? It is very durable, and we get them in the mail all the time. This design uses only one envelope, including the adhesive strip ( if you are using a new envelope ). For the purpose of this design I used a new envelope, to make cutting and photographing easier and to show how you can utilize the adhesive strip for assembling the wallet. When possible, I suggest using a recycled envelope from a package someone sent you. You can use clear postal tape to assemble the wallet.
Note: If you can find one with a clear window, you could somehow utilize that portion to display your drivers license once assembled, but the cutting would need to be modified for this purpose.
If anyone can add to this design, I would love the feedback. Ideally it would be better to be able to fold the envelope and only do a few cuts. Maybe someone with origami knowledge can help us with this idea?
