For the cake table buy a brown tablecloth or buy brown fabric and lay across the table (cupcake). On top of that lay a smaller pink tablecloth (frosting) and then sprinkle confetti or sequins on top for the sprinkles. Cover with a clear plastic tablecloth. Hang white Christmas lights around the room - place brown bow in between the lights. Tie different colored balloons at each chair to look like sprinkles.
