My mother hung a red ribbon adorned with gold walnuts in the kitchen. It was family sitting around the kitchen table. It was parents sharing their faith. Keep the two sides together because you'll need the sets for good fits, then clean out the shell. Paint the walnut shells gold.
Acrylic paint works best.
Use Old Testament passages that foretell the coming of the Messiah. Put a thin layer of glue on the shells. Put the two halves on each side of the ribbon, hold together until the glue sets. Glue the halves to the ribbon. Open this one Christmas Day.
