WINTER HEATING PAD Finished size is approximately 9in x 17in. This adorable heating pad is basically a bag with two ties at the top. You heat up the heatable insert that you will make following the instructions. The insert is filled with either whole flax seed, or rice. Once you heat the insert in the microwave, put it into the quilted bag, loosely knot the ties at the top, and enjoy! The pattern also includes instructions for making your blocks into a wall hanging!
