I'm not exactly an expert on bow making, but I can give you a few tips. First, you'll need some ribbon and scissors. Cut a long piece of ribbon, about twice the length of the tree. Then, make a loop at one end and tie it in a knot to secure it. Next, make a second loop and pull the ends through the first loop to create the bow shape. Finally, attach the bow to the top of the tree and adjust the loops and tails until it looks perfect. Good luck!
