That is an interesting principle, TT and CL. Now that I have completed phase I of the album project, I find I have 15 photo albums, and all the pictures are in albums, except some from my folks, which are still their property which I have at my house for safekeeping. When they pass, I will revisit how many to keep and make new albums with the ones I keep.
But this has allowed me to make finite the photo universe. I now can say, do I want to devote 15 albums worth of space to this? Or do I want to purge some of the photos (give originals to kids, maybe) and get down to 10. What is my maximum acceptable album number? Is it 20? 30? Surely not more than that. What if I do an album a year from now on, or two, and I live another 25 years? That's 50 more albums on top of the 15. Surely that is too many.
So I think the idea of containing is brilliant. I once helped a friend with her closet--she had 125 golf shirts. I said, "How many golf shirts are you willing to have, wear, care for?" I don't remember the number, but she got rid of a lot of golf shirts that day.
So I like this file cabinet idea a lot, Terry.
