Paint the backside of both paper plates and the Styrofoam cup silver.
Turn paper plates over. Twist newspaper and glue it inside one of the plates. This will give the plates some cushion and filler, keeping them from collapsing.
Glue the plates together, silver sides facing out.
Cut the Styrofoam cup in half, keeping the top half, discarding the excess. Glue small craft jewels around the cup and glue the cup to the top of the saucer. Glue a large craft jewel to the top of the cup.
Glue craft jewels around the outside of the saucer, leaving about an inch of space between each one.
