To make a wired ribbon bow for your Christmas tree, you will need the following materials: a roll of wired ribbon, a pair of scissors, and some string or ribbon for hanging. Begin by measuring out a length of ribbon that is approximately 18 inches long. Cut the ribbon at this length, and then take one end of the ribbon and fold it in half. Now, take the folded end and wrap it around the center of the ribbon, creating a loop. Repeat this step on the other side, making a second loop. Next, bring the ends of the ribbon together and tie a knot to secure the loops in place.
