I don't think you can improve on the color combination Stampin' Up! chose in the catalog, so I followed right along for this card.
The Love Notes Framelits and the Sealed with Love Stamp Set (Sealed with Love Bundle) as well as the Sending Love Designer Series Paper Stack make such cute Valentines. There are dozens of ways to use these items and so many possible combinations of sentiments that I think you can make a card or treat for every kind of Valentine you have! I also used the stitched circle framelits. I just love the added texture it gives.
