from the 2016 Occasions Catalog. It can be purchased as a Bundle or separately. As a Bundle, you also get the Party Pop-Up Thinlets Die set to go with the stamp set.
The colors I used are Tempting Turquoise (base of my card), Daffodil Delight, and Melon Mambo. I used the Lots of Labels Thinlits Die to stamp the words "It's Time to Celebrate with Cake" with Archival Basic Black ink. Then I colored in the words with markers. I stamped slice of cake with Melon Mambo.
Inside, I used the template and used a mask to cover up each word by using a Dauber to color in the the Happy Birthday cake inside.
