Glitter christmas balls are a great way to add a festive touch to your holiday decor. To make them, you'll need some clear christmas balls, glitter, glue, and some small decorative items to place inside the balls. First, fill the balls halfway with glue and then add your glitter, making sure to coat all sides evenly. Then, place your small decorative items inside the balls and fill them to the top with glue. Finally, allow the glue to dry completely before hanging the balls up on your tree.
