As I have been browsing Etsy, I have found a number of talented people cutting shapes from cute fabric to make even cuter appliques. I think these would look great on a canvas reusable shopping bag. Simple but fun. I have seen apples (the ones in the pic are from Northern Warm Things Etsy shop) but also super cute birds, trees and owls, mostly utilizing great patterns. An idea would be to make the appliques from cute fabric, but also sew the canvas bag and apply them before sale, instead of selling the individual appliques, which is already being done.
