My reception will be a tented outdoor reception. The tables are 60" rounds with ivory tablecloths and coral colored napkins. The centerpieces will be low on the table with lots of color and they will have a very casual feel to them that gives the appearance they were just picked. Ok, so that paints the picture a bit for you. Now, my question is, do you think having 2 votives at each table will be enough? Or would 4 be better?
