Step 1. First you'll need a heart template. We searched "heart template" online and printed out a few different sizes to use as templates. Trace over your box.
Step 2. Punch in the nails with your hands (adults should do this step) all around the heart as shown below.
Step 3. With one color string, tie off to one nail and string in a criss-cross design. When you want to add another color, simply tie the first string to another color and continue. When you're done, tie off the string to one of the nails and snip off any tails.
