Round floating candles can be used in table centerpieces to achieve many different looks.  For an elegant look, submerge your favorite flowers in glass cylinder vases filled with water.  Then, place round floating candles in the vases.  Use just one cylinder vase or use a few in various heights to add more depth.  Finally, to complete the look, place votive candles around the cylinder vases.  Round floating candles are available in different colors and sizes, so there are unlimited possibilities to what you can create.
