This card is a simple one we made at my home school kids' class recently. It uses an old stamp set from Sale-A-Bration from last year - sorry! The hearts are stamped with Polka Dot Punches (SAB 2009) and punched out with the Full Heart punch. If you don't have this stamp set, it would look equally as cute to emboss the hearts with one of the Stampin' Up! embossing folders or Texturz Plates.
You could easily have put "Happy St. Patrick's Day" from Teeny Tiny Wishes stamp set for the sentiment, but I chose "Good Luck" from Fundamental Phrases because it could be used year round.
