A shower brunch or luncheon: a gift and dessert table across the top and four round tables of eight. The guest of honor sits at the front table facing the room so gift opening is visible from every seat. Small enough to arrange in one sitting; the chart mostly keeps the mother-of-the-bride and the maid of honor from seating people twice.
