A bit of advice from a variety of party tips and tricks books: incorporate mirrors into your decor. You may be surprised to find how much depth reflection may add to a look.
Take a cue from the photos below. Anything from table top mirrors and frames placed beneath single centerpieces, to large mirrors as statement pieces in the reception space are fabulous ideas. Show off those gorgeous florals you paid so much for, add to your wedding theme with marvelous frames with mirrors instead of photos, or double the glow of the candlelight from all those candles burning away.
