Lucklily I measured before I started and realized it needed to be a little smaller... Hereit is, still pending as I type...
Here's #2... I made it a little smaller... 8 1/2 x 4 for the red piece. That way you don't have to slice down the long side of the card stock. You can get 2 fronts AND another one at 3 1/2 or still have a good size scrap left over.
