I have one filled with wheat and a handful of cloves.
Very useful. Hubby uses it everyday on his aching back and neck. Just pop it into the microwave next to a small mug of water for about 3 mins. The water is to prevent the bag of wheat from overheating. We all know that there must always be water in the microwave oven.Most of the time it's in the food that we heat up. Since the wheat is dry, half or a quarter mug of water should be placed in the oven next to the wheat bag. This is for those who are not aware of the fact. Not trying to be too clever. Lol!!
