Things You'll Need:
* 100% cotton fabric in any pattern (20 by 9 inches)
* 8 cups of rice and flax seed (any proportion is fine)
* Herbs you like such as, cinnamon, lavender, chamomile, lemon grass, rosemary, peppermint or spearmint (optional)
* Basic sewing materials (needle and thread or a machine if you like
Fold the top down. It will look inside out at this point. Sew along the right side and bottom edge. This will result in a long pocket that you'll be able to fill with rice, flax seed, and herbs later on.
Snip the corners on the top right, bottom right, and bottom left. This step will make the corners lay flat in the final product.
Turn the material inside out.
Tuck the remaining flaps into the pocket. Then sew the end closed.
Take good care of your heating pad. When you microwave it start with 1 minute. You can always reheat it up to 5 minutes, but WATCH it as it heats to make sure that the fabric doesn't scorch. Wear it over your clothes to protect your skin as well. Clean it by using a damp towel to wipe it, and your heating pad can last a few years. And that's all you need to know to learn how to make heating pads with rice. Good luck!
