We are having what I believe is known as a banquet set-up, which resembles a cricket wicket - 1 long bridal table along the top, plus 3 legs, kind of like an E.
I hadn't planned on having table number at all, since there's only 3 tables and if you put the bridal table on your chart, people can figure out their location based on that orientation, but my fiance was surprised to hear this and would like table numbers.
So, here we are. I am thinking big wooden numbers, but show me your inventive and creative number solutions - I wish to be inspired!
