#1. Buy it. I found these burlap votive holders on ChezRenee but I'm sure you can find numbered votives on any of the big craft sites. Clearly you need to have an idea of how many tables you will be having and it is best to overestimate in this case. The best part is that this is a hot ticket item and you can sell them after the wedding (or gift them to an engaged friend)!
#2. DIY part of this idea. If you have a desire to personalize your votives with table numbers, names of cities, hobbies, or even use photos then this idea is for you. Simple choose your votive, real candle or led candle and finally paper for the wrap. You can buy wraps or make your own with vellum paper.
