My centerpieces are going to have fake flowers under water with a floating candle at the top and some river rocks at the bottom... but as I was thinking about the flowers and water - I got worried. Are "silk" flowers really silk? Silk and water don't mix....so does anyone have experience with flowers under water? I'm not even sure my flowers are "silk" but to be safe...I am thinking I will take a petal or leaf from each of the flowers and test it because I don't need a last minute disaster! However, if anyone has any helpful hints or lessons learned, I'd love to hear them!!
