Ah, a bow for your Christmas tree topper, a classic touch that can add a finishing touch to your tree. To make a bow, you'll need some ribbon and a bit of patience. First, cut a length of ribbon that's about twice the size of the topper. Then, fold the ribbon in half and tie a knot at the center to create a loop. Take the ends of the ribbon and bring them together, creating a bow shape. You can then use wire or a hook to attach the bow to the topper. And voila, a beautiful bow to complete your Christmas tree!
