So tonight I made the cutest birthday card. Embossed happy birthday on the white card. I used green ink on a sponge to make it stand out. then I put green crdstock with a die cut "boys rock" in white on it. Unfortunately, since I was in such a hurry to get to the party, I forgot to take a picture! Guess that means that I'll have to make another one!
Update- here's some others that I did using the same technique.
