Heres a tip to keep those bags organized. First separate the bags by size. If you have one bag that is bigger and sturdier than the others use this as your storage container.
Fold the large bags in half and place in the sturdy bag. Flip the smaller bags upside down so its easy to see and retrieve. Otherwise the handles just get in the way and get caught on the other bags. Whatever fits in your one bag is what you keep.
