This was one of the first projects I did, and one of the most involved. It was for an Indian wedding in Chicago, and each piece was a different color that you would find in an antique map. They needed 450 of these!
Some pieces are not pictured (yet). In addition to the invitation and the RSVP shown, they also had a card with directions, a map to the venue, and a card for the bridal henna ceremony. This was all contained in a pocket on the back of the invitation.
We went with digital printing to more easily print several different colors, and because 450 invitations is a LOT, but all of the paper was a soft metallic ivory. As digital printing is not 100% opaque, it created a really nice sheen, since you could see the metallic through the ink.
