Create a canopy. Hang it from a hoop suspended from the ceiling to form a column. Place in front of small white lights to create a soft glow. Instead of a bouquet, carry a family Bible, a basket, a wreath or a single flower. Skip the aisle runner.
Balloons are an economical decoration.
Many balloon providers can create an arch for your dance floor or entry. Sprinkle confetti or potpourri over the table top. Cover with a glass top, lace or tulle. Create your own guest book by covering a scrap book or journal with satin or linen. Use printed sheets instead of renting tablecloths.
