Here is a card that I just made for Nickolas' friends 7th birthday party tomorrow. I can't take full credit for this, I did "case" the idea from someone, just can't remember who's blog I got it off of (Sorry!).
The front squares are punched out and the football is stamped on the inside of the card.
SU Colors Used: Cajun Craze, Early Espresso, and Very Vanilla
SU Stamp Sets: Cheery Chat and Sporting Goods (both retired)
