Gather some colorful items that the birds will eventually enjoy along with round cake pans or a 9x13 or something similar. Arrange the items to your liking and fill with water 2/3rds full. Tie a knot in rope, heavy string or hemp like I have shown, and submerge the knot into the water. Set outside to freeze or in the freezer until solid. To get the decoration out of the pan you may need to run warm water on the bottom of the pan. Hang outside and enjoy watching the sun dance on the ice. The first picture shows what it looks like when I first hung it on the tree. The second picture shows after a week of the sun's kissing.
