"Quilling or Paper Filigree is an art form that involves the use of strips of paper that are rolled, shaped, and glued together to create decorative designs. During the Renaissance, French and Italian nuns and monks used quilling to decorate book covers and religious items. The paper most commonly used was strips of paper trimmed from the gilded edges of books. These gilded paper strips were then rolled to create the quilled shapes. Quilling often imitated the original ironwork of the day. The name quilling is said to be derived from the fact that the nuns and monks originally used feather quills as their tool to roll the paper."
