The first time I used the die I cut the design using glitter paper from Michael's that has a variety of colors. I had a little trouble finding the right color to use as a mat but settled on the Stampin' Up! Wisteria Wonder. I believe the die cut sentiment is from Elizabeth Craft designs.
I cut a second piece using the glitter paper but this time I added it to black card stock and I like it better. The "Happy" and the "birthday" are from two separate dies.
