the invitation opens vertically
the first card, smallest one, will be map, then rsvp, and then with the largest one being the announcement.
the largest card is inserted into a pocket, and two slits are made on the pocket to make room for two smaller cards. i kept some space in between each cards to emphasize the layered look.
a simple tag is used, but can be replaced with any design request.
i think it's also nice if open horizontally
