Day 16- wedding centerpiece idea

I wanted to accomplish something quick and easy for the wedding today and I'd seen a pin about submerging silk flowers in distilled water for center pieces. My tall, thin vase is currently occupied with flowers; I tried a larger jar. I arranged the flowers in a circle since I knew I didn't have enough to stand them up as the pin demonstrated. I also wanted to let the flowers sit in the water and make sure that the flowers weren't changed in any way while they sat overnight (we may be able to set up at the wedding venue the day before the wedding). I think that this is a good possibility for center pieces.. thoughts anyone?
