Create a heart-shaped template, or print out the heart garland template, and place it on a stack of four sheets of card stock. Staple the center of the hearts and cut out the shapes.
Make a 1-inch vertical cut at the pointed end of a heart; cut heart to about 1 inch wide all the way around the inside. Make two 1/2-inch horizontal cuts from the center of the point of the heart. Repeat with other hearts.
Link two hearts through the cuts at the points; glue and trim the cut ends to create a point. Continue the process until all the hearts linked.
