For the card I did the Polished Stone technique first. After it dried I cut the hearts out with the Heart to Heart Punch. Stamped my images and assembled my card.
For the luminary I punched the top and bottom with the Pinking Hearts Border Punch. Punched out each side with the Heart to Heart punch and stamped inside the hearts with the matching stamp from the Love You Much stamp set.
