Or what are some of your chaotic ways to bookmark?

I've recently found small joys in using cute Pokemon cards as my bookmarks! I dabble in collecting One Piece cards but not Pokemon so I'm not as attached but still love them. I got a bunch of bulk cards from my brother so I've just been slotting them in everywhere that I've lost track who's in where. I think I like the idea that I have cute little Pokemon living in my books now.
