My suggestions are photography related, so please don't skewer me for centering my comments around photography! I make my living as a photographer, and I shoot a LOT of weddings. Anyway, there are centerpieces, and then there are "table arrangements". There is a difference! There are some really neat things that you can do with pictures as a part of your table arrangements.
A lot of people think of centerpieces as just one item. But for just sa bit more time and a little more money, you can create gorgeous arrangements that add a huge visual impact to your wedding reception.
Think of building a centerpiece arrangement in layers. You may have a flower arrangement in the center, surrounded by table candles, and glasses filled with candy, or miniature baskets filled with specialty teas, chocolates, etc. for guests to take with them.
One neat thing to add to a layered arrangement is pictures of you and your fiance on each table. I do something for my clients called "Table Images", and they go over very, very well with guests. We basically take a number of images from their engagement shoot (i.e., 15 tables = 15 different images) and those images are produced on black beveled polished wood backboards in 5X7 size. They are held on miniature easels on the table in or near the centepieces. If you have a friend that's good with a camera, they can help with this. Or talk to your phoographer.
Sounds kind of strange having pictures of yourself on tables, but I guarantee you they will disappear. Relatives and friends grab them. Anyway, nestle in among the centerpieces, and near candles, etc., a nice black and white image really imparts a nice atmosphere to those sitting at the tables. Eventually, once people realize each table has a different image, they'll go from table to table looking, and it gives them something to talk about.
Some of our clients put framed 8X10 and 11X14 prints all around the reception venue, and people seem to have a great time looking for the images. Then the framed prints are given to parents and grandparents as a valued keepsake. At the wedding I shot this past Saturday, the bride and groom had 5 black & white 8X10 prints framed at the signtaure table in really nice silver toned frames. Then at the end of the wedding, the pictures wre given away.
Someone above metioned bowls with candles and flowers floating in water. Those look beautiful!
We've had couples also do the following:
Centerpieces with little teddy bears dressed in sports team outfits for local college and pro teams. Those got snagged!
A couple very much into fishing bought fishermen and fisherwomen figurines and had pictures of themselves hanging off the poles in the shape of different fish.
Very tall glasses filled with Hershey's Kisses - kids love these!
Tiny envelopes embedded in the centerpices (if 8 people were seated at the table, there were 8 envelopes), and they had a kind of suprprise announcement. Whoever had a specific envelope got a dinner certificate fot two at Olive Garden, etc. Someone got a spa treatment. Another person got a blockbuster family gift certificate, etc.
A LOT of weddings here in Florida have a beach theme. So we constantly see very unique sea shell and flower themes with beautiful sand candles, pictures, and beach themed favors (remember, think in layers).
Then when I shoot weddings in other parts of the country, sometimes I see very seasonal themes especially if it's close to the holidays.
I have yet to see a black and white cow theme
