Create a template of a heart, about 1 1/2 inches wide.
Cut it out with a utility knife, and trace onto heavy card stock.
Copy it at 80 percent, cut out, and trace onto decorative paper, such as wrapping or origami paper.
Cut out both hearts, and use a glue stick to secure smaller patterned heart to center of the larger one; let dry.
Finally, trace the bottom half of the inner heart with a utility knife, cutting through the card stock beneath. Then your valentine can slip pages between the hearts.
