MATERIALS Baby leg warmer or old sock Bakers twine 2 cups uncooked white rice Empty toilet paper roll tube 10 drops of essential oil, optional or 1/4 cup lavender buds, optional TOOLS Scissors INSTRUCTIONS Tie up one end of a leg warmer tightly with bakers twine. You may skip this step if you're using a sock. If you're using lavender essential oil in your homemade heating pad, place the rice in a large bowl, add about 10 drops of lavender oil to it, and stir well. Or if you're using lavender buds, add about 1/4 cup and mix well. You can pour straight from the bag in the next step, if you're not using them. Stick an empty toilet paper roll tube in the open end of the leg warmer or sock to use as a funnel. Use a spoon or small measuring cup to pour the rice mixture in through the tube. Tie the end off tightly with more bakers twine, and your microwave heating pad is ready for use. How To Use Heating Pad For Heat Therapy Place the rice heating pad in the microwave along with one cup of water for 1-3 minutes. This will add moist heat and keep the rice from scorching. Remove the rice sock from the microwave and shake to evenly distribute the rice. Check the temperature of the bag to make sure it's not too hot. Apply the warmed heating pad to the desired body part.
