Did you ever get a highschool memory book? For your Senior year? Similar to that. There were spaces to write in, next to tabs on the pages where you could put in various items.

I went to Walmart, all they have is a book that has plastic protectors in it. That's it. 1 size, 6X6, 12X12, etc, nothing custom.

"what about page protectors that have pockets/sleeves?"

Of various sizes. Yes. However, I wanted a more all natural feel. So non-plastic. Maybe some kind of page tabs that could hold a variety of items.
