There's a short video on how to make a roller, below. If you have an exercise ball, you can use that instead, however, it will provide different feedback.
If this is a new process for you, consider watching first. Then, you can follow along with just the audio, because you'll know where you are going. Feel free to use the ideas here as the inspiration for your own creative exploration.
