Serve in colorful plastic beverage glasses. Attach large dots or stripe stickers (available at office supply stores) to the glasses, and let guests write their names on the stickers to identify their glasses.
For fun, rub the cut side of a lime or lemon on the rims of the glasses, then dip rims into shallow dish of coarse red sugar. Garnish with fresh cranberries on a beverage pick. If desired, thread sew-on gems, jewels or elegant beads (available at craft stores) onto thin silver wire, and wrap around stem of each glass.
