I used Lawn Fawn's Blue Skies stamp set and coordinating die set. I love the Lawn Fawn line--they have a lot of stamp/die sets.
The kraft cardstock is 4x4. I used the die to cut a cloud out of the blue paper and placed white behind it. I stamped the balloon with black and used the die from the set. The "thanks" stamp is also from the set, which I heat embossed with white powder.
Merry Christmas to all!
