Here is a sweet little 3x3 note using the Party Wishes and Balloon Celebration stamp sets. These are both great sets that can be found in the Occasions Catalog and both are available in bundles with coordinating punches.
For this card I began with a 6x3 piece of Watermelon Wonder cardstock scored at 3" and folded in half to create my card base. I cut two pieces of Whisper White to 2-7/8" square for my top and inside layers. I stamped the small balloon image from Party Wishes in Watermelon Wonder and their tails are in Memento Tuxedo Black as is the sentiment from Balloon Celebration. The inside is stamped with the small candle border image from Party Wishes. I love how this sweet card turned out!
I completed my project by creating a matching envelope out of the Watermelon Wonder envelope paper with my Envelope Punch Board! Love how it brings everything together.
