I bought a pair of dark wide leg jeans and wore my beige canvas tote. It hangs low because it is pretty big. Anyway, when I got home, I noticed that the color on my jeans had rubbed off onto the bag, creating a stain!! What can I do to remove this? It is such a dark color, and I don't want to create any further stains on the bag? Does anyone have any suggestions? I would appreciate it!
