I work as an aide in a elementary school. During the move from our old school to a new school, I was given a box of old greeting cards.

I used some them for decoration for my classroom(these were the ones with writing on them), but I still had a box of cards that was just too pretty to throw away. I can up with the idea to fold them in half and to glue the the sides down. They made perfect bookmarks for the children to use when they visit the library.
