Tyvek Lunch Bag

Tyvek is a strong, tear and water resistant material used for FedEx mailers and housewrap. I took apart a brown paper lunch bag and sketched out the shape on a flattened Tyvek mailer, then used my sewing machine to attach the seams (glue would work, too). The resulting lunch bag won’t last forever, but maybe it will last until you get your next scrap piece of Tyvek.
