Here's another idea for using the Punch Party stamp set. I got the idea from the greeting to make the hearts into smiley faces because I'm weird like that. I never know what is going to pop in my brain, LOL.
Normal-ly (heh) I'd use traditional colors but it somehow seemed right to go with bolder colors. Like I said, I never know what is going to pop in my head!
I stamped the hearts all over the card base in Magenta Madness, Coastal Cabana, and Granny Apple Green, then added the faces with a black Stampin' Write Marker. This is really just about the simplest, cute card you could make. The only way to make it simpler would be to stamp the greeting right on the card base instead of cutting it out and popping it on dimensionals.
