I have used Creative Elements on my card but you can use any stamp set with an image that will stamp on all three layers. you can step the card up by using some Embellishments but I haven't used any as I like the card as it is that way you get the full effect of the stamp.
Stamp Set: Creative Elements, Petite pairs
Ink: Crumb Cake, Island Indigo
Card stock: Island Indigo, Whisper White
