1. Choose the ornaments that you want to use. There are a variety of different sizes, shapes, and colors to choose from. Some people prefer to stick with one color scheme, while others like to use a mixture of colors and styles. 2. Start at the top of the tree and work your way down. This will help to ensure that the ornaments are evenly spaced out and that the tree looks balanced. 3. Use hooks or strings to hang the ornaments. Be careful not to damage the tree or ornaments while hanging them.
