Sectional Hot or cold pack

Have you ever used a rice bag? They are wonderful.  If you don't know, a rice bag is a bag of material filled with rice.  You can put it in the freezer to make a cold pack or in the microwave and warm it to make a hot pack.  My favorite place for a rice bag is around my neck.  The problem I have had is that the rice all falls to the ends of the bag so none of it stays right behind my neck but falls in front of my shoulders.  My son also gets a lot of neck pain and headaches from a whiplash injury, and wishes he could have heat or cold right where it hurts and have it stay there.  So I made some different varieties of rice bags to share with you.
