I have 1 small and 1 medium cafe bags. Someone mentioned recently that they used a large organizer pouch as a divider in a certain bag. I decided to try a medium pouch in both my cafe bags as a divider and also as security for those loose items in the largest section. It fits horizontally in the medium, and it fits vertically in the small. I also like the idea of criss-crossing key straps to help to hold things inside, but the medium pouch will be even more secure. Thank you to whoever suggested those ideas.
