I found a similar card to this one on Pinterest (http://www.pinterest.com/pin/392165080023198958/).
I have the Swallowtail Butterfly stamp from Stampin' Up, and decided to do something similar. For this card, I stamped the swallowtail and sentiment images with VersaMark, and then embossed with a Recollections Sapphire embossing powder. The card base is 5 x 6.5. The blue mat was cut a 1/4 inch smaller. I trimmed the butterfly at a slight angle to 4.5 x 4.25, and the sentiment to 4.5 x 4 3/8.
