Once the hearts were cut out, I used a guillotine cutter and cut it into four pieces 5 1/2" x 4 1/4" to make four fronts and trimmed 1/4" off two edges. That allows the red card base to show.
A Divine Swirls folder was used to emboss each of the four fronts. Then I added a small piece of baker's twine and a pre-made bow.
A smaller heart was cut then pop dotted for dimension. I coated the small heart with Crystal Stickles.
This idea came from a Stampin' Up demonstrator's blog.
