Wedding candle centerpieces can be different styles, heights or floating. Here I've attached a short pillar candle with floral clay to the bottom of the bowl. Then pour the colored water in the bowl.
You can add other elements, such as floating rose petals on the surface of the water.
Colored round or flattened marbles can refract light and add another cool element to your wedding candle centerpieces.
I simply put a handful in the bottom surround the pillar candle.
The light from beneath show off all your special touches.
