I have a March bride who wants a tropical wedding for not a lot of money. Don't ya love it? We're having trouble deciding what cost effective flowers can be used for the pew clips that will keep a tropical theme. Any suggestions? Her colors are purples, hot pinks, and greens. Using orchids, mini callas, amaryllis, lilies as the focal flowers. These being too expensive to be used for cost effective pew decor, I need some other ideas.
