We had our ceremony on a beachside terrace overlooking the sand and waves as sunset approach.  We chose to keep the ceremony decor minimal to hilight the beautiful horizon.  Here is a close up of flowers we used. 

 
The backdrop for their ceremony was simply adorned with ivory rose petals scattered in the aisle and four tall glass vases sitting on white pedestals flanking the altar and aisle.  The vases contained sand and seashells and light brown manzanita branches that emanated from ivory majolica roses, gardenias, and pale blue and green hydrangeas.
