You make these with material and fill with rice. You heat them in the microwave and put on tired aching muscles or around your neck to help that stress headache go away.
You need a piece of fabric about 15 inches long and 6 to 7 inches wide. The best types of fabric are cotton or towelling. Fold material in half and stitch around the edges leaving the end open. Tuck edges in and stitch down the middle of the bag. Fill each tunnel with rice (not the quick cook type). Stitch the end closed.
To use warm:
place in microwave for 1 or 2 minutes. Check as temperature depends on your microwave.
To use cold :
Place in ziplock bag and put in freezer for 2 hours or more.
I am pretty sure that, if you will be quite honest, you will admit that a good rousing sneeze, one that tears open your collar and throws your hair into your eyes, is really one of life's sensational pleasures.
