Tolsby is a very cheap photo frame that can be bought at IKEA. If you add a plastic cross-stich canvas to it you can easily get a cool earnings organizer. The organizer will be also a nice display for them.
All you need to do to get this awesome organizer is to cut a 4×6 inch sheet from the cross-stich canvas and put it to the frame. After that you can start filling it with earnings!
