Working in a library like I do, you have access to bookmarks that have been left behind. If they are not claimed then after awhile they become fair game. It seems like a lot of people go to England, buy bookmarks and then proceed to lose them. Sometimes I will theme my bookmarks to the book that I am reading. My lovely red Chatsworth bookmark (another English destination souvenir left behind) holds my place in The Mitfords because of the link to a Mitford sister, Deborah, The Duchess of Devonshire.
