Here's a unique card that was swapped at convention. I wish I could give credit to the demonstrator who made it but the card is a friend's and all I did was take the photo. Isn't it clever though?? The card stands up when fully opened (see last photo). The mechanism to stand it up is simply an extra scalloped circle (see middle photo). I love creativity!
