Years ago, I had fun upcycling t-shirts into shopping bags at my retail store. It was a big hit with the customers, who appreciated having reusable options to put their purchases in. I sewed the under-side of my bags, which you may also do. But below is a description of how to make fringe at the bottom and tie it closed with knots. That option is great if you don't have access to a sewing machine, or if you want your kids to help make the DIY t-shirt tote bags. Either way you decide to make it, your bag will be a great conversation piece at the store, especially if you use a t-shirt that has a great saying. Happy Upcycling!
