Flowers across mantles provide a great statement piece to impress your guests with for your reception and a photo backdrop for your first dance and father-daughter dance. The mantle flowers can be symmetrical, asymmetrical, all across, one-sided, just in the middle, on just the sides with an empty middle, garland with floral pops, or just greenery. Although it is most common for people to do some sort of flowers and greenery across the mantle shelf, you are not limited to staying in a straight line. Flowers can be arranged to look natural and growing, in a diagonal, or in any shape you can imagine really. Another fun element is to add candles, mirrors, or letters to your mantle. If you are having an indoor wedding, a mantle can be a great arch alternative for a ceremony backdrop.
