Here is a card I created for the same challenge that I put Gavin's scrapbook page in. We just had to use at least one heart stamp to do the project. I love this card, the size of it just makes it so cute. It is only 4 inches in diameter but it still packs a good punch. It would be so much fun to receive something like this on Valentine's Day.
Products used: CS - Bazzill, Punch - Fiskars, Ink - Memento, Stamps - Hero Arts, Brads - Making memories, Flowers - Prima, Ribbon - ? Note: I used the Storybook Cricut cartridge to make the yellow scalloped circle.
