This card is one that was demonstrated at a Stampin' Up party a while ago. I found the original in my card stash and thought it would be a great way to use up some lightweight solid paper from some of the stacks I have on hand.
The reason I consider it a postcard style card is because the card itself is a single 5.5 x 4.25" piece of cardstock rather than being folded.
I used Stampin' Up stamps and ribbon from Ribbons and Bows Oh My!.
