fabric & handle. versatility is a must for me when it comes to these types of bags. i hate it when i can't sling totes over my shoulder (especially in mpls, where we wear jackets and coats two-thirds of the year). perfect for the farmer's market or trips to the post office (in my case). looks like a cool d.i.y idea to try, but they are just $29-$39 for this tote shopping bag style.
