This eye-catching ornament strikes a festive note as a yard decoration -- make it a day or two ahead so it will have plenty of time to freeze. Feel free to improvise with any colorful natural materials you have on hand.
Place the pan on a flat surface. Arrange the orange rounds and pine branches in the pan and add enough water to cover them. Sprinkle on the berries. For the hanging cords, lay one end of each piece of twine in the pan, submerging it at least several inches. Let the pan freeze outside (or place it in the freezer).
Remove the ice block from the pan (run warm water over the back if needed) and hang it up outside.
