I used a variety of sizzix products to make this Sizzix Movers & Shapers Pro Die Set - Card, A6 Gate Fold & Heart #2 Card.--I then used a fiskars punch to create the scallop on the edges.. Replaced the heart for the front with the Classic icons one and inked the edges with glitter (shows up better in person).
Inside I used Sizzix Sizzlits Die Set 3PK - Cupid Bow & Arrow w/Hearts Set, Sizzix Thinlits Die Set 7PK - Heart, Keys & Tags, Sizzix Bigz Die - Classic Icons,
I also stamped and heat embossed "you hold the key to my heart" inside (easier to see in person.
