Sensational Centerpieces

One of the DIY projects I am most looking forward to is our centerpieces! We are going for a reception room that is romantic beach elegance. The room will be all white with hints of gold. Candles will give a soft glow. To illuminate the room, the centerpieces will be candles.

I have found so many inspiring photos on the web. I originally wanted one large hurricane vase, filled with a little sand, an off white candle, and a starfish. Something similar to the picture below.

Then I saw the image below and thought I must add lots of votives around the main hurricane centerpiece.

Then I saw this image and thought, I must add a few white shells at the base, with the sand. it seems like my centerpieces are ever evolving.

Lastly, I saw Mrs. Lemon's amazing centerpieces, and it got me thinking, should I do clusters of candles? I realized at this point I had already bought the hurricane vases, so I had to let go of the idea of Mrs. Lemon's beautiful candle clusters.
