What i did for my beach wedding seating chart. Buy a bag of starfish (dried out of course). Get a lot of ribbon (the color of your wedding) and tie the name tags onto the starfish. I put the names on the front and their table numbers on the back. Then you get a box, put sand in it and stand the starfish up in the sand.
Our best for your best. The Wedding Guest Book from @artifactuprsng allows for the display of your favorite photos along with space for handwritten notes. Get started with as few as 10 photos and let your guests fill in the rest.
