Finish off that ceramic Christmas tree or project with a duck treelight. Perfect for the ''six geese a-laying.'' Do NOT use any silicon or acrylic based glues (such as epoxy or super-glues) with the Plastic Christmas Tree bulbs as the synthetic glues can eat the bulbs. A white school glue, such as Elmer's Glue-All (Elmer's Glue), is perfect for use with the Plastic Christmas Tree Ornaments. Elmer's Glue will not permanently glue the bulbs in place, thus preventing damage to the Ceramic Christmas Tree should the bulb be mishandled during packing. In addition, the use of the a white school glue would allow changing of the colored ornaments at a future date.
