I have a pile of tees from various road races and have always said that I'll turn them into a tshirt quilt... but that may never happen, so I'm doing the next best thing and upcycling them into market bags to take to the farmer's market!
This is an easy project that's so low sew that you could even do it by hand if you wanted to (or maybe "have to" because you don't have a machine).
P.S. If you're like me and hate to waste anything, check out my dog toy tutorial
to use up the scraps from this project ;-)
