Yes...what she said. That is what I do with mine. If you have trouble keeping it together you can get a Sally Clip (jumbo clips) to help hold your bow together as your needle sits through the center. Then get some wire and wrap it around the center. This will help you practice making your "M" creases.
I have some detailed pics in this section how I used to make them when I was just learning. This proved to be a great tool for me. I no longer need those training wheels anymore.
