How so much debris got into that bag is beyond me. But after pulling out a few stamps to use and having to clean them off, I decided to clean the bag full and sort them by colors. It was a yucky job, but I knew it would be worth it.
(FYI, the time I spent was indeed worth it, but I only got through about three-fourths of the bag before I felt like I had turned into the stamp zombie. So I'm still not finished.)I have managed to add some more things to the pages of one book in the last week. Stamps, postcards, old envelopes, photos, anything that might be postal related. For now, they don't seem to have any rhyme or reason. But I have high hopes that it will somehow all pull together over time.
