A free sewing tutorial from Evil Mad Scientist Laboratories. A bicycle frame lunch bag you can sew that will hold your lunch perfectly. This bag is designed for a standard “entree” sized plastic container. The bag is made from three pieces of fabric: an 8″ x 8″ square, an 8″ x 13″ rectangle, and a 3″ x 22″ strip. Canvas (shown here) is a nice material to use, but any sturdy fabric like oilcloth or vinyl would work as well.
