I'm a firm believer that a tall centerpiece on every other table breaks up a space visually which is helpful when an event is in a tent. The bride wanted a vintage garden look and the iron candlesticks we had in our inventory fit the occasion perfectly. We only needed to paint them a creamy white. The "drippy" effect of the greens certainly softend the look.
The low arrangements were of the same materials but without the green foxtail. They had their own iron garden containers that coordinated with tall pieces. The guests were able to take home the centerpieces because they were designed in their bowls or on plates.
Renting containers from the person who is supplying the florals is an economical way to bumb up the look of a wedding.
