To make lighted Christmas balls, you'll need a few supplies. First, you'll need some clear glass ornaments. Then, you'll need some battery-powered fairy lights or Christmas lights. You'll also need some spray paint in the color of your choice. Once you have all of your supplies, follow these steps: 1. Start by spraying the inside of the ornament with the spray paint. Be sure to get a good, even coat. Let the paint dry completely. 2. Next, carefully insert the lights into the ornament.
