Isn't that stamp the greatest?? I fell in love with it immediately. It's designed by Jane Davenport and is available for purchase on the Stamping Bella website (if you've never browsed Stamping Bella's, there are TONS of cute girly stamps-- all on unmounted rubber).
For this one, I incorporated the tiny hearts onto an old button card and stitched them in the center to make them look button-esque. I decided to go with a sewing theme.
