The first thing your guests are going to want to know as they arrive at your reception is where they're sitting and who is at their table. You must conduct the delicate balancing act of having everyone feel comfortable while encouraging strangers to interact with each other. There are a lot of different ways to get people talking. Skip the boring signs on the table and get everyone in a pleasant mood right off the bat!
Even though your invitations requested an RSVP, it's likely some of your guests won't have done so. Avoid setting your seating chart in stone until a few days before the event so you can deal with any last-minute stragglers.
Try and incorporate your wedding's theme into the seating chart itself. For example, if you are having your wedding in the Napa Valley (an ever-popular destination for couples), designate each table with a different wine region, such as Bourdeaux or Riesling.
Assigned seats are a great delivery system for personalized gifts, as well. Leave small bottles of champagne in front of each spot, or add that extra touch with a personalized shot glass!
