I used the Swirly Doo Valentine Stamp Set from SP& Company and really liked how the stamp on the inside of the card mimicked the strip of patterned paper on the front of this card.
The small circle embellishment was included in the paper pad as a punch out. I embellished the center with rhinestones and popped it up with pop dots to give it some dimension.
