Tip: Making a Microwave Heating Rice Pad

Making a Microwave Heating Rice PadIf you want a really simple and quick microwave heating pad, this is a frugal way to throw one together.


  • 1 tube sock
  • 4-5 cups of rice
  • essential oil, dried lavender or dried rosemary (optional)


Fill a tube sock with 4-5 cups or rice or until the sock is 3/4 filled.

At the end of the sock tie a knot and pull tightly so the knot can't come undone easily.

Optional: Add a few drops of an essential oil of your choice. Add a few sprigs of dried lavender or rosemary.

To Use:
Place the rice filled sock in the microwave for 3-4 minutes. You can also place these in the freezer to make a cool pack.

These are great to put around a sore neck or on the small of a sore back. Also great during pregnancy. Make a few of them and put them on all your sore spots. These are much cheaper than the therapy bags sold in stores and work the same.

Note: Don't let the pack get wet.

Tip: Heated Rice Bag

To make a nice heated rice bag, use fleece and make it as big or small as you like. Just put the white rice into the rectangular fleece bag and stitch it up. I'm sure you could also use a tube sock and just stitch up the end. Then you can put it in the microwave for 2-3 minutes to heat it up and put it on sore muscles or arthritis areas. (Also, our Chihuahua loves it to warm up in the winter). The rice keeps the heat for quite awhile and it is also moist heat. We have one rice bag from 15 years/ago that my mom made and it still works great!


Tip: Natural Heating Pad

Take a tube sock of whatever size you would like and fill 3/4 full of instant rice. Put in microwave for 1 to 2 minutes. You will have a natural heating pad. Have kids or anyone decorated it with stamps or clothing paint.

Tip: Bed Warmers

They are telling us we are going to get our first snow tonight here in Colorado and I was thinking that I needed to do something to warm up our bed to keep us warm at night when we turn down the furnace. So here is what I am going to do. I am going to get some of that polar fleece and make some bed warmers.

Make a square out of polar fleece and fill it with clean kitty litter. These then can be popped into the microwave and put in our bed to warm it up before we get in. Since the kitty litter will hold the heat, it should keep us very warm this winter.

Question: How To Make Homemade Hot/Cold Packs

I need a pattern for a hot/cold neck pack. Thank you.

By cotygirl from Canada

The quickest way to make a hot-cold pack is by taking a pillow case (made of cotton or 50/50 cotton-poly) then pour in one or 2 boxes or bags of any type of rice. (Minute rice OR regular). Then tie a knot on the end of this pillow case so the rice stays in.

To heat: Simply microwave it to heat the rice up. Usually for 2 or 3 minutes. You can also freeze it. But I prefer to instead use this rice-bag for only heating, then use a bag of frozen peas or corn for cooling. Buy 2 bags of peas & switch them out when the first starts to melt. When you no longer need the frozen peas (or corn) you can eat the veggies. (as long as they stayed frozen!)

I like the way you can take the warm rice-bag with you in the car, unlike a heating pad, this bag is portable!

If you know how to sew, you can turn the empty pillow case inside-out, then sew 2 seams up the middle of the pillow case 1 inch apart, then with scissors cut between the seams so you'll have 2 thin tubes, then fill with rice & knot the ends. If you use a pillow case you will have lots of room to move the rice around for your best fit & comfort. Buy your pillow cases at Second Hand at any Thrift Store or Garage Sale for 50 cents.

---> If they get dirty, simply un-knot the pillow case then dump the rice into a container & wash & dry the fabric then refill with the rice again. Easy, Fast & Cheap... Plus, if you are poor, you can buy the rice & frozen peas with Food Stamps & eat them when you no longer need the hot-cold packs!

* If you want a nice scent, add several tablespoons of Dried Lavender, Whole Cloves or slightly crushed Cinnamon Sticks to the Rice.

Question: Rice Heating Pad Fabric Content

I just bought fleece fabric to make rice pack cover, but neglected to check fabric content. Must it be 100% cotton to be used in microwave?

I'm not sure about the fleece. I use socks for mine and although they are cotton, there is always the stretchy threads in them..?? Try heating a small scrap of the material and see how it does.

Question: Making a Hot/Cold Neck Band

I see the pattern for the neck band made from a sock. I was wondering if you have any other styles or shapes that I could try. The bands are the ones that you heat of make cold and are filled with rice.

That should not be a problem since you're only heating it for a minute or so in the microwave.

Question: Microwave Heating Pad Exploded

I made a heating pad with rice out of a small square pillow case that I bought at the dollar store. I ripped out the zipper and sewed it up for microwave use. I used the pad maybe 20 times and then it exploded in the microwave. The rice was smelling like pop corn each time. When it exploded, the rice was burned. I used just plain white rice and heated it for up to 5 minutes each time as it was about 5 lbs of rice. And it wouldn't feel good unless it was heated for a few minutes then turned over and heated another minute or so. Has this happened to anyone else? What did I do wrong? Material type, type of rice? Heating length? (but I needed it hot, not just warm). Thanks.

I also agree that 5 minutes was likely too long. I have one my neighbour made for me; it is filled with wheat and she put 3 or 4 cloves in it for the aroma. I have had the cloves overheat and char the flannel, and make a little hole. I only ever heat it for three minutes, and then re-heat for 2. Mine is about 1 pound, maybe two. I suspect that 5 pounds is too big, and parts of it overheated before the center got warm, and this caused your explosion.

Question: Adding Vanilla Scent to Rice Heating Pads

Can you use vanilla essential oil purchased from the Dollar Store, or vanilla flavored tea bags, or vanilla scented potpourri in the rice heat pad?

The last two, yes. Anything you put in with a dry grain and esp' in a fabric bag must be dry. That sounds like a wonderful project though. Try peach and orange cinnamon tea and let us know how it went?

Question: Cold Pack Pattern for Kids

I saw the cutest pattern for a cold pack for kids that was made like a chicken (it reminded me of the owl patterns you see everywhere). It was so cute. I wanted to make some for my great niece and great nephews who are always getting boo boos. Now I can't find the pattern. Please help me find a pattern and help the kids with their boo boos.

Don't know about a chicken, but I use a Boo Boo Bunny. Instructions are here:
I stitch the face instead of use the glue on eyes and such so it is okay for the littlest child to use. Use it dry, wet, cold or warm to help whatever the boo boo might be. It holds an icecube very easily and absorbs the water as it melts. Good luck

Question: Rice Filled Heat Pad Sweats When Heated

I made a heat pad with rice, but when I first got it out of the micro wave it was sweating. Why?

By Cindy W.

By Abigail A. [5]11/21/2014

Because rice has moisture in it, even though it seems dry. Incidentally, did you know that if popcorn was entirely dry, it wouldn't pop? It's that tiny bit of moisture that heats up to make it explode.

Hi there! We use men's tube socks or women's knee high socks for heat packs (one of a pair that remains with no holes or tears) and fill with dried white or brown rice or dried barley. Works like a charm and if the sock happens to rip, we save as much rice or barley as possible, boil it up and add it to our dogs' food before starting all over with another stray sock. Can't get much thriftier than that! :) Good luck!

Question: Which Types of Rice Are Safe to Use in Microwave Heat Pads

I've made heat pads before and had no problem with them, but I do not remember what kind of rice to use. I'm concerned about fire.
I bought Carolina Jasmine enriched Thai fragrant long grain rice (Thai Hom Mali Rice) and Lundberg California white Basmati aromatic long grain rice. Does anyone know how safe these are?

I don't know about the rice, but I do know that deer corn works great. The corn has a moist heat and holds up very well, no worry about fire.

I found that if you place a small cup of water in the microwave as you heat your rice bag the rice will get that burnt smell and it helps with the moist heat. Also, I made a fleece sleeve cover for my rice bags, it helps hold the moist heat in longer .

Beans, and cheery pits work best, as they are a larger grain and hold their heat longer. Does anyone have any ideas for non-stop use . I injured my back and I am non-stop using my rice heating pads and the microwave heating is slower when you are trying to heat up more then one heating pad.

I thought of setting up a steaming pot on the stove top to set more then one heating pad in so I would have instant heated pads on hand as one or more cooled down. But I'm not sure if that would actually cook the rice or not?

Any ideas?

For a medicinal heat pack for arthritis and rheumatism, dry roast in a clean pan equal amounts of fine diced old root ginger and rock salt till the ginger is golden and dry. Make a thick cotton case large enough to hold the mixture so that when flat the heat pack is 1 inch thick and seal. Make another as a washable case to put over it.
This can be heated in a microwave oven for 1 to 2 minutes to the desirable temperature. Do not over heat as salt can retain high heat and cause burns on fragile skin. Place on affected areas to soothe the pain. Store in dry cupboard when not in use.

Here's a coincidence! Not 30 minutes ago I finished two hot pads for my Chihuahuas. I used 100% cotton fabric and 100% cotton batting (thin). I cut 6 layers of fabric using a plate for the shape and 2 layers of the batting. Layer 2 fabric, 1 batting, 1 fabric. Sew around the rim of all and leave a 4 inch opening. Turn it inside out so the batting has fabric on each side. This gives you a low temp side with the batting, and a higher temp side with the fabric. I stuffed them with cheap, bulk rice and then sewed the opening shut. Popped them in the microwave for 90 seconds.

A word of warning--a friend put his nylon or polyester socks in the microwave to dry them after he got caught in the rain. They melted and started a fire in the room.

I've been thinking of finding a cotton shirt and sewing on a liner with vertical tubes to fill with rice. I'd have the tubes run around the shoulders and across the back. My bursitis just yells for it. --Stone in OKC

My sister made some of these with a medium weight cotton fabric. She used regular rice and added some essentail oil like peppermint and lavender. They smell great and are very soothing. Then she sewed a little pillowcase for it out of some old upholstery that was pretty. That way, when it gets dirty, you just take off the pillowcase and wash it.

I take a terry cloth tea towel. I fold it in half length wise. I then sew it in thirds. I then fill it about half full of field corn in each of the three pockets. I then double stitich around the towel.

I heat in the micowave about 4 miniutes. When it no longer keeps the heat or it gets dirty, throw it in the washer. Lay it out to dry (DON'T) put it in the dryer.

This works great on a knee as it is big enough to lay on the top of the knee and around the sides. Enjoy!

RE: Homemade Lavender Heat Packs

Buy some lavender buds, you can find them and flea markets, or herb fairs. You only need a few, then go to a bulk store and buy flaxseed. I do this because you want the lavender for the smell and the flaxseed to fill the space up at a reasonable price. Lavender is expensive. Use about 1/4 to 1/2 cup lavender and the rest flaxseed. You can also add a few drops of lavender essential oil. (10/04/2004)

Heat Packs

Heat hot packs or foot warmers in the microwave! These can also be made cheaply by using some fabric and dry beans or rice. (12/20/2004)

By Robin

RE: Homemade Lavender Heat Packs

I've used a combination of the feedback you've already gotten. Use whatever fabric conatiner works for your ultimate purpose: something long, flexible and cylindrical for a neck warmer, or more of a pillow if that's what you need. A "dogbone" shape is good for neck support and warmth while sleeping. Use lavender flowers, not seeds. They have the essential oil with the scent. You can also use some essential oil as well, or a less expensive fragrance oil. Use rice as a filler. Flaxseed has its own properties that can add to a special pillow, but if you want something economical and that works, just use rice. (12/20/2004)

I use a sock. I fill it with a mixture of rice and lavender buds. Then tie it off with a rubber band and a pretty piece of ribbon. You can place this in the microwave for a couple of minutes, or the freezer for a few hours for a cold compress. This feels really good on sore joints or mussels. (05/23/2005)

RE: Homemade Heat Packs

I have Fibromyalgia and I wouldn't be without my rice packs. When my muscles start to tighten-up. I pop them into the microwave for no more than 2 minutes and then apply them to the offending muscle.

I've made my own. If you can sew a straight stitch on the sewing machine, you can too. Measure the area where you will want to apply the pack. If for example the area is 12 inches by 13 inches, you will need a piece of material 25 inches by 27 inches. You will have about a 1 inch seam. take your material over to your ironing board. With the wrong/inside of the material facing you, fold the 'top' edge of the material down about an inch & iron it flat. Do the same with the 'bottom' edge of the material. Now with the 'right'/outside of the material together, fold the maaterial in half. Pin the short side together, so you will have an envelope effect. Straight stitch the pinned ends. Turn the 'envelope' inside-out. Press the envelope flat. (All this ironing makes the sewing easier as it makes your project lie flat & easier to sew.) Fold the envelope in half & iron it,then fold the half in half again & iron that. Take some pins and put them where the ironed folds are. Go to your machine & sew from the top down to the first corner on your right. When you get to the corner, lift up your pressure foot, leaving the needle in the material, turn the material so you will be sewing along the bottom edge. Sew slowly so that when you get to the place where the pins are in the ironed fold, aso you can swivel the material & after having removed the pins you can sew from the bottom to the opened top. When you get to the top, you now have sewn in a U shape. Swivel the material so that you can go back down on the line you have just sewn to the bottom. When you get to the bottom swivel the material so that you are sewing along the bottom edge until the next set of pins in the middle fold. Sew up & down again & make another U.Now you have 2 'pockets' completed. Do this twice more and when you come to the top on the left side you will have 4 'pockets'.

Now you can fill them with rice. I use Jasmine rice as it doesn't have an old musty smell after a few uses (my rice packs have been in the microwave about 500 times. I've tried adding lavender to them but haven't been able to get the right preportions.) I use the top I've cut off a plastic coke bottle for the funnel. Fill the 'pockets' about half-way full. Carefully lay the pack down so that you won't spill all the rice out. Push the rice down to the bottom of the pack & pin along the top edge of the rice NOT the top of the pack. Use as many pins as necessary so the the rice does not escape & get in the way of you're sewing the final seam across the top. I always make one row of stitching across the top & then make another row of stitching just to make sure. I have wrapped them in a towel on occasion to keep them from getting dirty. But I finally make 'covers' for them. Now stick them in the Microwave & ENJOY. (06/05/2005)


RE: Homemade Heat Packs - Vanilla Bean?

I've recently woken up with a n incredibly sore neck and have since been looking for an easy way to make a heat pack. I've tried the rice idea. Unfortunately, I used poly sock, so that was quite disastrous! I now know that cotton is the way to go. (07/27/2005)

By Sarah

RE: Homemade Heat Packs

I've had several relatives who have used homemade microwave heat packs, but they were filled with either rice or corn -- and I thought they were extremely uncomfortable. One day I was in the mall and asked one of the vendors who sells these what made hers so soft. Ever since, I've been making them for friends and family, and I fill mine with a combination of oatmeal and flax-seed.

I also use about a half-bag of that scented ground potpourri (for sachets) you can buy at WalMart in the crafts section, per heat-pack. (It comes in lavender and other scents like Gardenia and Cinnamon.) Mix up about 2 cups of the oatmeal with 1-2 cups of the flax, and the sachet-potpourri, and fill about 3/4 full in a long sewn-together tube of fabric (about 30" x 6 or 7" folded in half), then sew ends together.

Microwave for one minute on high at first -- then just 30 seconds to warm it up each time after it starts cooling down within that same hour. I wouldn't live without these in the winter -- and I LOVE how they smell so great too! (11/08/2005)

RE: Homemade Heat Packs

I am probably older than most of the posters (67), and have suffered front pinched nerves and back problems since I was 20. Finally wound up with cervical spine surgery.

BUT, a zillion years ago, an old Italian Grandma helped me out by heating "kosher" salt in a pot and filling a white cotton sock with it. She sewed the top and that was it. Of course now you can heat the sock with the salt in it in the microwave. I never used any scents, just plain old "kosher" salt. (12/31/2005)
