Alright, let's get started. You'll need: 3 coat hangers, some string or wire, and a few decorations like lights or ornaments. First, take one of the coat hangers and bend it into a circle, leaving the hook on the top. Then, take another coat hanger and bend it into a triangle shape, and attach it to the circle with some wire or string. Finally, take the third coat hanger and bend it into a star shape, and attach it to the top of the tree.
