Microwave heating bags help soothe aches and pains and can be less expensive than over-the-counter pain relievers. Using fabric and rice or corn, you can make these bags at home and even sell them at craft shows or give them to friends and family members. The fabric keeps the rice or corn from burning your skin, but the bag remains hot enough to help reduce aches and pains.
Cut a piece of fabric into four 9-inch squares.
Place one square on top of another square. Sew three sides of the squares together with a tight zigzag stitch, leaving the fourth side open. Repeat this process for the other two squares.
Pour rice or seed corn into one of the squares. Fill it two-thirds of the way full.
Sew the open side of the filled bag closed with a tight stitch.
Place the filled bag into the other sewed square. Sew the opening closed with a tight stitch, also sewing the edge of the filled bag with the closing seam to keep it from moving around.
Place the bag in the microwave for 2 to 3 minutes to heat it or place it in the freezer to cool it and use it as a cold pack. Place the heating bag in a zipper-sealed bag to keep it clean during use.
