First paint the terra cotta pots on the outside and inside. Allow to dry completely. A second and third coat may be required. 

Make sure to clear the hole in the bottom of the terra cotta pot using a toothpick.

Then cut a piece of ribbon approximately 6 inches long. Thread one end of the ribbon through the hoop end of a bell. 

Position the bell in the middle of the ribbon. Fold the ribbon in half and knot the ribbon just above the bell and again about one inch above the first knot.

Next thread the ends of the ribbon through the hole in the bottom of the terra cotta pot. Use tweezers if necessary to help pull the ribbons through the hole.

Once the ribbon is pulled all the way through the hole, add another knot close to the cut end of the ribbon to create a way to hang the ornament. Make sure to trim the ends of the ribbon to clean up any raveling pieces.

Finally decorate the ornament using buttons and tacky glue to create the look of a Christmas tree.

Allow to dry completely before displaying or packaging as a gift
