I finally made a card using the balloon pop-up die from the Balloon Pop-Up Thinlits Dies. I also used the stamp set that coordinates with the dies, Balloon Adventures. You can purchase them together as a bundle, and save 10%. I CASEd the outside of the card from one that Nikki Spencer made.
The inside of the card is pictured below. I had so much fun decorating the inside. Everyone that has seen this card in person has LOVED the inside of the card.
