Table numbers are an important piece that cannot be left out of the decoration scheme. They are functional for direction purposes and can reinforce the wedding theme.
Personally, I like framed table numbers that add some elegance to the table.
Also, if you want to make them a little more personal, or connected to the theme, you can add fun backgrounds.
If frames aren't your forte, then you can go many different routes.
For a natural, or outdoors wedding, you can take out two birds with one stone by using the floral centerpiece as the table number.
Another option is having interactive tables numbers.
If none of these suit your fancy, then you can have stand alone letters which still get the job done.
Wishing you a happily ever after!
