Papel picado ("perforated paper") is the Mexican folk art of papercutting into elaborate designs. The designs are commonly cut from tissue paper using a guide and small chisels, creating as many as forty banners at a time. Common themes includes birds, floral designs, and skeletons. They are commonly displayed for Easter, Christmas and the Day of the Dead, as well as during weddings, quinceañeras and christenings.
