Microwavable Rice Heating Pads

Printer-friendly versionSend by emailPDF version

We love the simple clean lines of these microwavable neck and lap/back heating pads. After under a minute in the microwave, you'll get up to an hour of safe, warm heat without the dangers inherent in electric heating pads: burns, fires and electrical shock. Electric heating pad cautions actually read: Never use in a situation where you could fall asleep. Hmmm... often falling asleep is my goal. These pads are not difficult to make, and are a useful gift for most any adult. They're good for muscle aches or when you feel a chill and don't want to turn up the thermostat. You can also freeze them for a pleasant cooling effect. Although, just typing that made me shiver. Add a drop of essential oil if you'd like a little aromatherapy.

Before you begin, measure the interior of your microwave oven just to be sure the lap/back pad will fit when folded in half (about 8" x 12"). Most microwaves will easily accommodate something of this size, but there are a few older and space-saver models that may require you to slightly reduce the size of the pad.

We show you dimensions and supplies for both a neck pad (22" x 8" flat) and a slightly larger lap/back pad (16" x 12" flat).

To give your heating pads as a gift, fold them up and tie them with a piece of natural twill tape. Pretty and practical!

Sewing Tools You Need

Fabric and Other Supplies

This project is a great for fabric scraps. You can use flannel, as well as quilting or décor-weight cotton. Just don't use anything with metal threads (unless you want a fireworks display in your microwave). We chose cotton ticking for its clean, fresh look and tight weave. Ticking is an old time fabric that was historically used for covering pillows and mattresses because its tight weave kept feathers, horse hair, and other fillers in place. Today, ticking has once again become trendy for design accessories like throw pillows, as well as for upholstery. There is something classically soothing about those woven stripes.

Ticking is available almost everywhere fabric is sold. We found good selections at both and Fat Quarter Shop. The ticking we used is not the industrial-strength mattress variety, but a décor-weight that has a soft drape after washing. As we always suggest, pre-wash and press your fabric before beginning this and other projects.

Neck Pad


  • ¼ yard of 44-45" wide cotton ticking or similar; we used a red stripe 
  • ¼ yard of 45"+ soft fleece or similar; we used winter white
  • One package of jumbo rick rack in red: this is optional, as is the size of rick rack you use
  • 7 cups of uncooked rice for filler
    NOTE: Corn is another option for a filler, just don't use the popcorn variety... feed corn is a economical option.
  • All purpose thread to match fabric; we used natural
  • See-through ruler
  • Fabric pen or pencil
  • Iron and ironing board
  • Scissors or rotary cutter and mat
  • Seam gauge
  • Seam ripper
  • Straight pins
  • Optional: Essential oil (we added a drop of vanilla spice or you can add a few lavender buds). You should be able to easily find a selection of essential oils in the organic section of most grocery stores.

Lap/Back Pad


  • ½ yard of 44-45" wide cotton ticking or similar; we used a classic navy stripe 
  • ½ yard of 45"+ soft fleece or similar; we used winter white
  • 1 package of jumbo rick rack in navy: this is optional, as is the size of rick rack you use
  • 6 cups of uncooked rice for filler
    NOTE: Corn is another option for a filler, just don't use the popcorn variety... feed corn is a economical option.
  • All purpose thread to match fabric; we used natural
  • See-through ruler
  • Fabric pen or pencil
  • Iron and ironing board
  • Scissors or rotary cutter and mat
  • Seam gauge
  • Seam ripper
  • Straight pins
  • Optional: Essential oil (we added a drop of vanilla spice or you can add a few lavender buds). You should be able to easily find a selection of essential oils in the organic section of most grocery stores.

Getting Started

Neck Pad

  1. Cut ONE 9" x 23" rectangle from the red ticking.
  2. Cut ONE 9" x 23" rectangle from the fleece.
  3. Cut TWO 25" lengths of the red jumbo rick rack.

Lap/Back Pad

  1. Cut ONE 13" x 17" rectangle from the navy ticking.
  2. Cut ONE 13" x 17" rectangle from the fleece.
  3. Cut TWO 18" lengths of the navy jumbo rick rack.

    At Your Sewing Machine

    From here on, the instructions are the same for both the neck pad and the lap/back pads (except as noted). We use ½" seams throughout.

    1. If you want to add a label as we did, add that first to the center of one of the compartments. It should be about 2" from the bottom at a minimum.
    2. Pin the rick rack to the two long sides, centering it on the ½" seam line (ie. the center of the rick rack should be ½" from the raw edge). Machine baste in place.
      Click to Enlarge
    3. Pin the ticking and fleece rectangles right sides together. Sew all the way around leaving about a 3" opening on one end for turning and adding rice. Remember to pivot at the corners and to lock your seam at either side of the 3" opening.  
      Click to Enlarge
    4. Trim the three sides without the opening, and clip the corners.
      Click to Enlarge
    5. Turn right-side out and press, folding in the raw edges of the opening so they are flush with the sewn seam. Your rick rack should pop out along each edge.
      Click to Enlarge
    6. Find the center of the neck pad and and mark with a pin. From the center, measure 5½" to either side and mark both of these points with a pin. These are the marks for the four rice compartments. 
      NOTE: For the lap/back pad, measure just 4" to either side of the center pin.
    7. Adding the essential oil is an option, but if you want to add it, now is the time. I used ONE drop for each pad and my whole sewing room smells wonderfully like vanilla spice.  If you're using essential oils, put the rice in a large bowl, add the oil and stir. One drop goes a loooooog way.
      Click to Enlarge
    8. Add rice to fill the first compartment. You want to be able to conform the pad to your neck, so don't overfill. We used about 1¾ cup for each neck pad compartment and 1½ cup for each lap/back compartment. I made a simple paper funnel to make pouring rice easier (a regular plastic funnel tends to clog). Hold the pad up vertically so the rice falls to the back of the first compartment you marked earlier, giving you a clear path to sew the compartment closed without sewing through any grains of rice. 

      Click to Enlarge
    9. Sew a vertical line of stitching at the first compartment line. If you used ticking, you have a line to follow from pin point to pin point. If not, you can use an erasable fabric pen to draw a straight line between the two points. Pin through both layers along the line and sew. Stop from time to time, with the needle in the down position, and shift the rice towards its compartment to keep the presser foot area clear. It's a bit time-consuming, but not difficult.
    10. The first compartment should look about like this:
      Click to Enlarge
    11. Repeat for the next three compartments. 
      Click to Enlarge
    12. When the last compartment is filled with rice, hand sew the the opening closed with a tightly-spaced slip stitch.

    Using Your Pads

    Since microwaves vary in how quickly they heat, start with 1 minute and see how it feels. The microwave we tested required about 2 minutes to achieve the desired toasty warmth. DO NOT overheat, you can scorch the rice. Once you know how long it takes your microwave to heat your pad, you can set that time for future uses. Do not attempt heat the pad in a conventional oven.

    You can also use this tutorial to make a simple cover for a heating pad. To do this, measure the heating pad and cut two rectangles from flannel or quilting cotton. Cut the rectangles two inches wider and five inches longer than the finished outside dimensions of the pad. With right sides together, sew along both long sides and across the bottom. Serge or zig zag the raw edges. On the top end, fold under ½" and press. Fold under an addition 1" to form a hem. Edgestitch the hem in place. You can add a ribbon tie or two if you'd like to hold the cover closed on the end after you slip the heating pad into place.

    My question stems from the type of thread to use to sew the bags together.  I have either 100% viscose rayon or 100% polyester.  I have heard both sides to not use rayon and not use polyester.  I am making handwarmers to give as gifts.  Please help.....

    Liz Johnson.Editor.Sew4Home said:

    @ Tina T - we traditionally recommend polyester.

    When filling with rice is there any way to make sure that the rice is distributed evenly throughout the compartments? Or do you just eyeball it? Thanks!

    Liz Johnson.Editor.Sew4Home said:
    Liz Johnson.Editor.Sew4Home's picture

    @ Chantel - as you see above, you fill one compartment at a time - so just make sure you're using the same amount for each compartment. The rice shifts and settles - so there will always be a bit of movement. But that's one of the cool things that allows the pads to mold to your body.

    with myself being such a worry-filled person I rembered how there was controversy about how rice had arsenic in it and quickly threw the pillow on the flirt. Will/can this pillow be harmful??

    Liz Johnson.Editor.Sew4Home said:
    Liz Johnson.Editor.Sew4Home's picture

    @ Roary - This type of heating pad is not harmful. The studies of rice and arsenic all center on cooking and eating rice or rice based foods.

    With me being overwhelmed with worrying of cancer I remembered how rice has arsenic and tossed my rice pillow on the floor. Can this pillow be harmful?

    Perhaps a silly question - are these machine washable with the rice? Or should you just spot clean? Thanks! Looking forward to making mine!

    Liz Johnson.Editor.Sew4Home said:
    Liz Johnson.Editor.Sew4Home's picture

    @ Meredith Smith - Yes, they are meant to be spot-cleaned - they cannot be machine washed with the rice inside. Some comments below have mentioned creating an inner lining pouch and then an outer sleeve that could be removed and wased. As we mentioned, that would be great, but you'd need to do an overlapped "envelope style" opening for the outer cover since any type of zipper or snap ... or even many buttons .... would not be microwaveable. 

    Liz Johnson.Editor.Sew4Home said:
    Liz Johnson.Editor.Sew4Home's picture

    @ glide - since most flannel is 100% cotton, it can be good choice, however, you'd want to make sure it was a thick flannel or use at least a couple layers. Many flannels are rather thin and would not work well; you need a fabric with a bit more substance.

    I am curious what brand or type of oils you suggest to use?  I have no knowledge in the essential oils area, lol

    I have used ground walnut shells from the pet supply store, this works as well as rice in my opinion.

    My daughter stole my last rice bag, and I'm looking forward to using your great design.  Does it matter whether you use white rice or brown rice?

    Liz Johnson.Editor.Sew4Home said:
    Liz Johnson.Editor.Sew4Home's picture

    @ Hi-Mom-B - We haven't tested with brown rice, but have read that most people use and prefer white rice because the brown rice sometimes gives off a less desirable smell.

    I recently made a few of these, but when I put them in the microwave, they got kind of condesate-y and wet. Any idea why or how to stop it?

    Liz Johnson.Editor.Sew4Home said:
    Liz Johnson.Editor.Sew4Home's picture

    @ MollyBail - Rice provides a natural, slightly moist heat. That's something many people like because it increases circulation and speeds recovery. If it's truly wet, you may be overheating it. The natural moisture decreases some over time. I'm sure it depends on how it's stored and how much moisture is in the air.

    Just a quick note if using field corn from farm supply it might be dusty.  I put it over an old window screen and  tried to get any loose dust off before making.  Also, at the farm supply store make sure and ask for plain corn and not sweetened.  Not having a farm myself I did not realize that some came with a type of molassas or sweetner on it sometimes.

    Just whipped up one of these myself with some gorgeous polished cotton of a print called "Winter Wonderland" (swirls of purples with white stars and snow flakes) and some natural coloured soft cotton lace on the edge.  I make these regularly as gifts, and usually use a few tablespoons of dried lavender buds (no essential oil).  I find the buds keep the hot pack nicely scented for quite a while, but when the scent fades, I add a touch of essential oil here or there on the fabric which freshens it up!

    My daughter, who has moved 3000 miles away, was looking for a heat pack recently like the one we had when she lived at home.  Of course, it remained at home as it belonged to 'the house', and not her.  I made her one of these for pennies and in less than an hour.  Have just shipped it to her for her birthday.  Awesome gift and great directions.  Guess what everyone is getting for Christmas next year????

    I'm going to make a template of my hand and stitch the outline on top of an additional piece of fabric.  then sandwich altogether so the rice will be on top and it can be used for a hand warmer for those with arthritic joints or hands. This way the warmer will not slide off.

    LisaTQF said:

    I've made and used these for years.  I was crushed the day I found out that my rice pack wound up in the wash with the sheets.  I caught it before it went into the dryer, and let it air dry on a sunny windowsill for a few days.  Believe it or not, it still worked!   ****However,****  after a few uses, I noticed that the grains of rice had turned to powder within the pack.  I was curious, so kept using it to see what would happen.  No rice powder has leaked out, it still heats up, but it loses heat much faster than when each grain of rice was intact.  It also has a faint smell now, but it will do until I can make a new one!

    I have made something similar but filled it with feed corn.   Mine has lasted for a long time.  What is good is it ends up smelling like popcorn.

    Can you use warming oil instead of essential oil ?

    Liz Johnson.Editor.Sew4Home said:
    Liz Johnson.Editor.Sew4Home's picture

    @ Brianna - we aren't familiar with use of the warming oil. Our best advice would be to make a small square sample pouch, fill it with the rice enhanced with the warming oil. Then heat it and see if you like the scent, and make sure it doesn't stain the cover - sometimes the other oils are more likely to bleed through, even in small quantities.

    Love this tutorial.  I am a little concerned about using rice since there's been so much news lately about arsenic in rice. I think I'll try buckwheat for the filler.

    JenJango said:
    JenJango's picture

    You're not eating it, pretty sure that the mostly-harmless-trace-amounts aren't going to seep through several layers of fabric and then your skin. You get more arsenic than that just walking on soil.

    I made one yesterday for me as a 'prototype' for Christmas presents. In place of the tag, I embroidered my name (with my moms sewing machine), and sewed that on. So far my mom and her fiancé have tried to steal it from me, so I think it'll work for good presents! Thanks for the easy tutorial!

    I noticed the buttons in the visual but not in the directions (unless I missed it). What is their purpose? I was at the throttling yesterday & bought a perfectly good percale striped sheet I can't wait to use it. It feels so good to reclaim our resources, save money & make practical Christmas gifts all at the same time :)) They are beautiful & your tutorial perfect for visual learners ( such as myself). Thanks Do you have a copywriter on this pattern?

    Liz Johnson.Editor.Sew4Home said:
    Liz Johnson.Editor.Sew4Home's picture

    @ Debbie Dee -- those aren't real buttons, they are the decorative heads on the straight pins. And yes, all projects and patterns on Sew4Home are copyrighted. I'm sure these pads will be a big hit as Christmas gifts.

    Hi, good morning. Is there any change in the rice used when the bag is washed?. This absorbs moisture and keeps his feature? 

    Thank you

    Liz Johnson.Editor.Sew4Home said:
    Liz Johnson.Editor.Sew4Home's picture

    @ remarquez1 - The bags are not meant for heavy-duty washing. There really shouldn't be an occasion for them to get super dirty, and so you should be able to be simply spot clean with mild soap and water without submerging them. When done with the spot cleaning, leave the pad out to dry thoroughly.

    Love this.  I've already made a lot of the pouches and am ready to fill them.  I happened to have a bag of dried lavender flowers I'd like to use.  How much rice would I eliminate in each pouch, if any to accommodate the lavender?

    Liz Johnson.Editor.Sew4Home said:
    Liz Johnson.Editor.Sew4Home's picture

    @ Susy B -- the amount of lavender is really a matter of personal preference as to the intensity of the aroma. We always use essential oils, so I don't have "real-world" test results for you. Others have recommended up to 50% lavendar to rice. However, you don't want to remove TOO much rice or the pad will feel kind of sloppy. Since you are making several, perhaps you can test it out with one, heat it up to see how you like it, and go forward from there.

    I received a couple kitchen towels as a gift that are that icky velour-type fabric. I can't stand the feel when I dry my hands on them, so I've been trying to think of something else to do with them. This tutorial fits the bill! They're big enough that I can use them to make bed warmers for winter to keep my feel from getting so cold.

    If it's not cotton, don't make it to microwave it. If you must use it, make it as a cover for packets of rice,flax,whatever, made out of cotton. Anything non-cotton will burn, scorch or melt in the microwave.
