I try to join the Card Chain Challenge every month because it is so much fun to send and receive hand made cards. We have choices of the challenge option that we'd like to do and I wanted to do the Aperture or Window card. I've used this beautiful Hero Arts die before, but I did something a bit different with this. As I was going through my stash looking for papers, I discovered a beautiful card (front only) I had received from a non-card maker. That became my window backing instead of making a card base from scratch. I used 3 dies and glued them together.
