Here's a custom wedding invitation I made recently for a couple in San Francisco. Donna and Matt had a red and purple color palette and a heart theme carried throughout the wedding. The bride wore these awesome Vivienne Westwood heels with hearts on them (like in this lovely Once Wed photo shoot), and their dinner reception was held in a red velvet room.
Each invitation set included an accordion-fold heart die-cut card, an RSVP postcard and a paper band to hold the pieces together. Envelopes had custom mailing labels addressed to each guest.
The couple loves Polaroid pictures and had a Polaroid photo booth at their wedding. I incorporated it onto their response cards, and guests could write them a note or draw a picture in the blank space.
