This is the Valentine's Day card I made this year. It folds up and then can unfold flat and also be folded into a heart shape with the hands coming together at the crown. It's 6 inches tall with the widths of the 2 different sizes coming in at 4 and 8 inches bringing it to a grand total of 48 inches in length. It's just plain old bristol board with inch wide pieces of bristol scored down the middle vertically to serve as hinges connecting each pieces and allowing the crisp folds.
It went over quite well. :)
