Made this for my in-law's 50th wedding anniversary next month. I love that DP. The card is 5.25" square (5.25" x 10.5") but instead of opening from the bottom it opens in the middle with scores at 3 inches from one end and 2.25 inches from the other end. The card is held shut with the belly band. You can't really tell in the photo, but the paper in the circle was run through the Cuttlebug. Made the 50 numbers with my Cricut machine.
