I was surprised Colton did as well as he did with this. I figured he'd smear it around and if I got lucky something in there might resemble a heart. He had a blast! He loved stamping the hearts and did a pretty good job. If you are doing this with older kids (or hell, yourself!) check for air bubbles on the tube before stamping, because that will fill in part of your heart when the stamping is done, but I just let Colton go to town until the paper was over saturated in parts.
He was having so much fun that I cut a second piece of paper in half and made Valentine's for the grandparents too! The paint does take quite a while to dry, so that left plenty of time to add glitter.
