Here is a sneak preview of our 2013 craft project. These string backpacks are made of canvas and seem to be just the right size for books, notebooks, cameras, binoculars, etc. I have adopted one of the prototypes and use it every time we travel or head to town. The logo is classic leather, similar to the Duluth Pack Company! In the photo below, Dave is securing the edges with pop rivets and fabric glue. Looking forward to sharing this great project with our guests this summer!
