Do you like this idea of a wedding centerpiece?

If your doing a beach theme Sand and pebbles would be a nice touch to add but I get what your saying if your going for the romantic feeling definitely flowers and floating candles are great! I LOVE THEM! Mix and match choose different flowers and arrange things one flower type on one Table one and the next on another. You can even add some glitter in the water that might look very nice to. If there kids around or your having a kids Table get them candy center pieces that match with your wedding instead of candles just to be safe hope all of this helps! I like your examples though there perfect and beautiful!
