I've been making these cards with my own twist for a while now. They're fun to make, and very personal. They do not open; they are just the front and back of heavy chipboard. I design the front and back (5x7 with 1/8" bleed) in Photoshop. For the back, I make an extra overlay of the lower edge element and duplicate it to make a pocket. After I print the cards, I laminate the printouts (front, back and overlay) on one side only. I then glue it down onto the heavy chipboard. On the back 5x7, I leave a bit of the lower edges where the overlay will be unlaminated so that it will glue on more securely. I then have a pocket where I can put a gift card. I've done these for weddings and birthdays. It's a fun way to give a gift card while giving a small keepsake also.
