I really want to know, what's in your collection?

One is to leave a note to remember the call number when borrowing books from the library, which will be used as a bookmark first and put away after returning the books; There is also a movie ticket collection, which can also be used as a bookmark; There is also a refill bag that can also be used as a bookmark; There are also fallen leaves in different seasons, sealed with wide tape and flattened as bookmarks. I think if I collect stamps, I guess stamps will also be put in the book as bookmarks. After all, it can be flattened and can be seen at hand every day. It's good to turn to a fallen leaf when turning over a book and recall the autumn whisper for a few seconds. ?
