The use of limes, lanterns and candle holders is perfect for this setting...all have a natural, rustic, outdoorsy element...which keeps with the theme and location of this event.
I love outdoor weddings, and I love it when elements from the setting are used. Have you decided where you are getting married? If you have, take a good look at the location and see what, if any, elements can be arranged, added, incorporated, etc...that you might not have noticed before. Looking at things from a different angle always works for me!
