This old custom is charming indeed: At the bridesmaids' luncheon, each guest pulls one ribbon from the center of a Bundt cake to find a good-luck charm and message dangling from the other end. Charms are available by mail order, often complete with fortunes, ribbons, and bags; we ordered charms but added our own messages, ribbons, and glassine envelopes. Ribbons can be color coded so single, married, and very young women will choose charms -- such as rings or baby carriages -- that are appropriate for their situations. Other popular charms include a coin (for luck), an airplane (for travel), and a telephone (for a special phone call). To assemble, bake your favorite Bundt cake, put the charms in the center, and drape the ribbons over the cake; fresh flowers provide decoration while hiding the charms.
