I haven't seen those anywhere. I checked with All Seasons rental, which is one of the larger rental companies that have more modern pieces, and they didn't have them. I would call them just to make sure and see if they have any suggestions on where you could possibly find them. But you may need to purchase them online.
Thanks ladies! Yeah Im looking at the website right now - who knows, may come across another idea of a tabletop centerpiece they may have there. If not, Im also thinking I may have to buy the candleabras. *shrug*
