Bethany from Finding Pins and Needles shows how to make a rice-filled heating bag. It’s a long bag divided into smaller sections so it will wrap around your body. You can heat it up in the microwave, a bit of Velcro will help it stay snug around your body as it delivers the therapeutic heat. Between uses, it rolls up for easy storage. Go to her tutorial.
