Start by making a small loop, this will be the top loop on your bow. Pinch the ribbon, twist it, then make another loop that is larger than your first one. Pinch, twist, and make another loop opposite of the last one.
Continue to pinch, twist, and loop until you have made 6 more sets of loop. Make each set of loops a bit bigger than the next. Make a long tail and trim the ribbon from the spool. Take a pipe cleaner and use it to tie off the center of your bow.
Next cut a long tail and add it to the pipe cleaner at the back of your bow.
