If you'd like to check the challenge out for yourself, you can see the post here.
Disclaimer: Sorry for the bad photo, I had a really tough time photographing this mini-card!
I used Papertrey Ink card stock in Stampers Select White and Raspberry Fizz. I used PTI Bitty Background Blocks to stamp the yellow pattern on the banner, and the "happy birthday" sentiment came from the PTI Mat Stack 1 collection.
Thanks for stopping by!
