Fruit instead of flowers: Fruit can also be a great centerpiece idea. By simply filling a glass vase with lemons you can create a masterpiece. This works for all seasons as well, use apples and pears for the fall, cranberries for winter and lemon, limes and oranges are perfect for summer and spring weddings. The wonderful thing about using fruit is the color palette you can create. Also, get creative, add candles or lights. Let your imagination work for you.
