No picture yet, but I have some tall rectangular glass vases that I'm putting 12 x 3" white pillar candles in with greenery halo at the bottom. Similar to the look attached! We are having 27 tables - 7 with the candles, 7 with those same vases but flower arrangements seated on top, 8 taller glass vases with curly willow and white flowers, 5 with short square glass vases and flower arrangement.
I don't have pics but we were at a wedding last winter that just used buttloads of candles (some real, some LED) of varying sizes in glass containers to match their shapes. super minimalist and so pretty.
Agreeing with the candles. We are going to have greenery running down both of our tuscan-style tables, however we are also going to have a ton of different sized candles. I think it would be just as pretty with simply candles. Only if your venue allows real ones, though (IMO)
