I am a person who uses a bookmark or I just remember the page. I hate dog earring books. I don’t like also leaving it open wide. If I don’t have a bookmark on hand, I would use other stuff to substitute it with. Or, this is the time I would memories the page number I am in. I don’t like dog earring a book, because it makes the book less sturdy. Chances are also, the dog eared part would be permanent. Anyways, here is a list of items, I usually use when a bookmark isn’t available.
1. A piece of paper or Receipts
3. candy wrapper
5. A piece of tissue Paper
