For an all-frills setup with little fuss, slip seating cards in between rows of ribbons. Cover foam boards (ours are 20 by 30 inches) with satin and grosgrain ribbons; randomly layer narrow ribbons over wide ones. Pin the ribbon ends to backs of boards, inserting straight pins at an angle to secure. Slip in envelopes by their flaps or bottoms.
