I never had a chance to play along with Verve September Release One Sheet Wonder challenge (VSSEP08) until now and I love the way my cards turned out. All four cards are made from only one 6x6 double-sided designer paper - although I added a ton of more cardstock for layering! Here are pictures of the individual cards so that you can see more of the details clearly. These could easily be made into SUO cards by eliminating the use of the CB embossing folder and using either plan cardstock or other designer paper!
Card 1: Card 2: Card 3: Card 4: I love the way these turned out so much that I'm thinking of making more in the other designer papers that use this same pattern (maybe more than just birthday cards too)!
