Glue fake flowers to the bottom of a tall vase (or to stones you could drop in), fill with water, and top with a floating candle. Gorgeous and you could use any color to fit the room you put it in for the bbw vases on my fireplace.
Put a piece of your wedding gown or veil into a necklace to remember it later - or make for your daughter to wear on her wedding day. Such a sweet idea!
