For this card, I used a 3 3/4 X 5 piece of Bashful Blue attached to a 5 1/4 X 8 Whisper White cardbase. The cardbase is adhered to a 4 1/4 X 5 1/2 piece of Basic Gray. I have been doing this a lot lately as it's a great way to use a white or vanilla card but still have enough weight to the card plus it still gives that border of color around the edge.
Happy stamping!
