I created my own background with a sponge, a MM ink pad and a piece of photo paper. I intentionally left the top part white so the happy would contrast with the card color.
Once dry, I cut it with the Memory Box Grand Happy Birthday thin die. I trimmed to sides down to 5.25 inches and adhered it to the card front.
I cut the stars with the Sizzix Stars #2 Originals Die using Basic Gray and Real Red card stock. They are held in place with a tiny white star brad.
