Here's two cards I did using subway art from free printables at http://anythingbutperfect.com/ . There are 6 colors of the subway art on the site but I used only 2 of them. The free printables are for framing as 8x10" but I printed them smaller to fit a card. I layered it with various cardstock and added a bit of ribbon. I used Viva Pearl pen in opal and black for the dots around the subway art and on the numbers. I only made a few of these for my sisters and my sons. I really liked the colors and the design of this subway art.
