Reception decor

You can buy these in bulk for cheap at Dollar Tree.

Renting. The votives with candle were $2 to rent, and they set up, light, and take down. I'm not much of a DIY bride.

It's through our venue who also handles flowers.

I bought the floating candles on amazon. The vases from the dollar general. I got the votives (candles and glass holders) from tableclothsdfactory.com

I'd get quotes from a rental company and your florist first. If you have a day of coordinator, they should be able to handle setting them up, lighting them, and dealing with them at the end of the night. If it's just you and your family, I'd lean toward renting them.
