These purses and briefcases may not hold guests' belongings, but they're a charming way to designate their seats (table numbers are written inside). To make, use 3 1/2-by-5-inch folded seating cards (we used pink for women, brown for men). Unfold cards. With a utility knife, cut 2 slits wide enough for ribbon in the fold, 1 inch from each edge. Insert ends of 3-inch-long ribbon into slits; it will stay in place without gluing or tying.
