I realized that I have very few birthday cards for kids in my inventory and thought the Custom Tee stamp set would be a great one to use for a few.
To add some splash to the backgrounds, I used the Happy Celebrations stamp set on two different layers of card stock behind the die cut shirt.
Custom Tee, Happy Celebrations
Real Red, Pacific Point, Tangerine Tango ink
Pacific Point, Real Red, Very Vanilla card stock
