I'm so in love with Etsy! Have you checked it out yet? So many amazing artists and one-of-a-kind goodies! Check out these ceramic napkin rings from BROOKLYNrehab . Imagine using these instead of table numbers, having each guests' napkin sporting the appropriate table number (so one table has all 3s or all 4s – you get the idea). You can also have them personalized with initials or dates if you prefer. Whatever you put on them, they make a cute little guest gift and a super cool detail to your wedding tables.
