My sister in law gave me a very nice wrap. You heat it in the microwave or place it in the freezer if you want a cold one... I love it so much I decided to try and make some for a few friends. It is a little different than mine as mine is quilted on one side. I didn't bother doing that part. So far I've made 3 and have 3 more in the making. They are filled with 2 pounds of rice with lavender (organic grown) and peppermint. Although I did make one without lavender as my friend is allergic to it. Hers has hops and peppermint. They all smell so good!!!
