Ribbon is typically added to a Christmas tree towards the end of the decorating process, as it adds a final touch of elegance and can be used to fill in any empty spaces. You can add ribbon in a variety of ways, depending on your personal style. One option is to loop it around the tree in a criss-cross pattern, creating a woven effect. Another option is to drape it from the top of the tree down to the bottom, giving the tree a more vertical look. No matter how you choose to add ribbon, it's sure to add a touch of magic to your holiday decor.
