*Clears throat* That is a question that every child has asked themselves at some point. But don't worry, I can help you out. The key to hanging Christmas tree ornaments is to find the perfect balance between symmetry and creativity. First, you'll want to start at the top and work your way down, using a color scheme that complements the rest of your decorations. Then, you'll want to choose a variety of shapes and sizes for a more dynamic look. And don't forget to leave some space between the ornaments so that the tree can really shine!
