Very slowly and carefully drill a small hole into each shell.

Paint the fronts and back of each shell with white paint. Allow the paint to dry.

Brush a coat of Mod Podge over the front of the shell. Sprinkle with glitter, shake off the excess and allow to dry. Repeat on the back (optional).

Apply two more coats of Mod Podge over top of the glitter to seal it down so it does not shed.

Loop a piece of wire through the hole you drilled. Leave one end longer than the other. Slip three large beads over both ends of the wire.

Twist the shorter wire tightly above the top bead and pinch the bundle of wire together with pliers. Bend the longer wire into a hook.

Let dry completely before hanging on your Christmas tree.
