Also, if working with young children, you might opt for plastic balls instead of glass. Some plastic models can open in half, similar to plastic Easter eggs, which can be easier to work with depending on your project. Also, if you want to break out from the glass ball idea, similar options include fillable flat discs and Christmas tree light bulbs with screwtops at the filling point. They also come with ornament hangers and are fun to make your own. Traditional filler ideas include photos, candy, pom poms, and glitter. For a more inventive spin, think about adding plants, yarn, and sequins. You can personalize unique ornament in minutes, making a lovely, customized gift. If emojis are not your thing, use green glitter and make the Grinch, try red glitter and make Santa Claus, or make reindeer using brown glitter.
