Very cute ideas there! I save all cards, you can punch out small faces for bottle cap pins, save another part of the same card for a backing to put the pin on,with large cards you could glue onto a cd for decoration or use on a homemade card front,use for all kinds of altered art projects, gift tags.
TFS that site!
