When deciding what kind of summer wedding theme you want to have, think of warm summer locales or ideas that inspire romance - flowers, the beach, a picnic, a backyard barbeque, an English garden, a Tuscan villa, etc. Choose decorations, flowers and invitations that correspond to the theme. With long, lazy days and lengthy, breathtaking sunsets, take advantage of the summer sunlight. For a casual wedding, plan a mid-afternoon tea luncheon while light is plentiful. For more dramatic romance, exchange vows on a serene evening as the sun sinks into the West.
