I'm considering doing small metal tree centerpieces, but wondering if I need anything else to go on the table. Should I just put one on each table? The ones I'm looking at are about 18 in high and have 2 tea light candle holders. (I'm at work and can't post pics) I feel like maybe there needs to be something else on the table but I was trying to avoid using flowers if possible. Any ideas? I'd love to see pics if anyone else has done this idea.
