I have two systems for images, neither complete, and neither fully satisfactory. I stamp off each image as they come into my possession as soon as I apply cling foam and trim. In the past I then put images in notebooks in categories with the stamps themselves in other 3 ring binders (I figure I'm old enough that if they begin to distort because of the way I store them, I'll either no longer care, and if I do, I'll have a reason to seek out replacements :-) I've been trying to convert my notebooks of images into card catalogs by topical area with only limited success. The sentiments I've stamped onto 4 X 6 notecards, put packing tape onto the card and relying on the cling properties of the cling foam and the packing tape I adhere the image to the card (so I can read the stamped image and have the stamp itself immediately available), and file them in photo boxes. Sometimes the stamps don't cling, and they don't sit in their photo boxes very elegantly, but it's increased my ability to find sentiments and use them. Previously, I had sentiment stamps in a 3 ring notebook and used a mirror to hunt for the sentiment I wanted. Not sure if my description quite captures the process, but I think the moral of the story is that there is no perfect indexing system, and one has to find one that works, then keep it up. The number of stamps I own has outstripped the time I have available for organized indexing and life's too short
