haramaki (tummy warmer) tutorial

I saw this post on Craftzine yesterday about the new Japanese fashion of wearing colourful haramaki aka ‘belly warmers’. I think this is the best idea I’ve seen in a long time! Ever since the advent of low-rise jeans, women have been stuck with a little cold gap between the bottom of our shirts and the top of our jeans. This is a cool way to cover that gap, and why import one from Japan when we can all make our own?

I whipped this one up this morning as a prototype, so I left it plain, but just imagine how amazing it could look if you freezer paper stencilled a funky design on the fabric before sewing it…


When it was finished, I tried it on and was surprised by how warm I felt – it really does work, even when it’s just made from 2 layers of t-shirt fabric.

To make your own haramaki:

You can use any fabric with some stretch, so you can pull your haramaki on and off. I used a knit jersey (i.e. t-shirt fabric).

You will also need a sewing machine with a stretch stitch (pictured below).

  1. Work out the dimensions you need. The height is up to you – I decided to go for an 8″ tall haramaki but you could make it longer if you want. The length of the haramaki depends on the size of your tummy..! Of course it would be easier to estimate for a skinny straight up-and-down Japanese model than for a regular curvy lady. I decided to make mine 30″ around (without giving too much away, that’s halfway between the measurements for my waist and my hips). If you want to wear it high up, make it a bit shorter than your halfway measurement, and if you want it to cover your hips, you may need to make it a little longer, depending on how stretchy your fabric is.

    To get the fabric dimensions, the length is 1″ over the length you decided (mine is 30″ + 1″ = 31″) and the width is double the height plus 1″ (mine is 2×8″ + 1″ = 17″). Cut your fabric to these dimensions and lay out as shown (right side up):

  2. Fold your fabric in half so the top meets the bottom, as shown below:
  3. Pin the 2 long sides together, all the way along. It’s better to space the pins more closely than you normally would, as the stretch fabric can get out of alignment more easily than a regular fabric:
  4. Sew along the line you’ve pinned. You have 1/2″ seam allowance, but that 1/2″ includes the full width of the zig-zag stitch, so you may need to practice on scrap fabric first to see which guide line to follow on your sewing machine. Trim the extra seam allowance after sewing:
  5. You have just made a long tube. Stick your arm through the tube and grab onto the far edge of the tube:
  6. Pull your arm back out of the tube, bringing that far edge of the tube back through the middle of the tube. Stop when the raw edges meet up, and align the edges:
  7. Pin the inner and outer layers together, all around the raw edge:
  8. To clarify, you should now have a tube that is half as long as before, made from 2 thicknesses of fabric. The pins should not close off the end of the tube:
  9. Sew around the pinned edge (again, 1/2″ seam allowance), leaving a gap of about 3″. Turn the harimaki right side out through this gap:
  10. Fold the edges of the gap under, and hand-sew the opening shut. That’s it! All finished!

I’ve been wearing mine all day and it’s warm and comfy and like having a hug all day long ๐Ÿ™‚
Please leave me a comment if you like this idea or if you make one!

    Love the tutorial, thankyou! My acupuncturist recommended I use a haramaki as my belly is chilly, common amongst those of us who spend a lot of time sitting in front of a computer – apparently we get blood stagnation in the belly which causes the chilliness, and the harimaki helps to improve the situation (along with chi gong and needles of course) ๐Ÿ™‚ So I’m off to dig into my fabric stash and make a couple this weekend – so they’re not just for pregnancy ๐Ÿ™‚

  2. Christine said

    I have made this, but with a slight modification – 3 layers thick. Was a bit of fiddling to work out how to do it best, but very warm – currently wearing it. Thanks heaps for the instructions. My mum has also knitted me a couple.

  3. Amy said

    Thanks! I was looking for a practical pregnancy gift for my sister-in-law, and couldn’t justify the boutique price of a tube of knit fabric. I’ll be making my own now, Thanks!

  4. Kirsten said

    Good Day,

    I just wanted to let you know that I have linked to this fun tutorial and hope to make myself one really soon as it is winter here in South Africa.

  5. rokuchan said

    If anybody out there wants to know how to KNIT haramaki, there is this one book, “cables on the go”, that shows a picture of a cabled neck warmer that works perfectly as a haramaki! All you need to do is use larger needles and yarn, and I prommise you it works!! (^_^) Though it only fits those who have about a 30 inch waist, so if you can calculate your patterns and how many stitches you need, then you’ll have to figure that out on your own. BTW, the pattern is near the end of the book, take it out from your library and find out!

  6. Tim said

    Very good tutorial thank you!

  7. Selina said

    Wish i’d seen this earlier, i bought two belly bands while pregnant and ended up having to re-sew them on an angle to make them sit right. could’ve saved time and money if i’d thought to make them from scratch.
    This is a great idea for pregnancy but will now continue to wear it while nursing, thanks for the tip from Tamara Watson XOXOX

  8. bellywarmerlover said

    Great tutorial! thank you so much for sharing this, I don’t have a sewing machine, but I have a black tube cotton dress( that I don’t use very often , I am going to try to convert this one into my own haramaky ^_^.

  9. Tracey said

    Thanks for this great tutorial! I used it for my first foray into sewing knits. I had trouble with the edges of the fabric curling up. Final result was slightly wonky and a little too big, but quite serviceable. My belly is warm and I’m inspired to try some more. Next ones will be slightly tighter, slightly taller (longer?). I need to taper mine because my hips are a lot wider than my midriff. I’m a plus-size.

    I had the best luck using the overlock stitch setting on my sewing machine – zig zag stitch wasn’t as stretchy. If you have overlock then use that. This would be a great project for learning to use a serger.

    Thanks!! I am going to make some for my little girl!! I hate how they cut clothes for pre-k girls these days they bend over and u see everything and they make the undies go down too!! This will be awesome and who knows start a trend. I also saw the “garden party” apron for girls too!! Can’t wait to sew!!

  11. vicky said

    Thank you so much – this is just what I needed – I’m going to make a whole wardrobe of these for the next few months ๐Ÿ™‚

  12. julie said

    thanks so much, my pregnant sister in law will love me.
    i could only find stretch lace and another stretch so i did it in those.
    it looks awesome with the deep brown fabric behind the lace, kind of like a corset.very dressy.
    thanks ever so much, great pattern.easy to follow.thrilled to bits.

    This is awesome! Those low cut jeans don’t work so well for those of us in the over 35 group. They are comfortable but too revealing. And the high waist jeans are even worse. This is perfect. I can still wear my lower cut jeans, be comfortable, and not look like I’m trying to wear teenage clothes! Genius!

  14. Sue said

    Thank you, the tutorial is great! I have made two so far and bought the cloth for a third one :).

  15. April said

    Thank you so much for posting this! I made a maternity belly band last night, before reading your tutorial, but could not figure out the right way to sew so it could be turned right side out again. I was very frustrated, but I found your tutorial, made the correction and it turned out beautifully! Kindest regards, and again, many thanks!!!!

    P.S. Ladies, for those of you sewing maternity belly bands, I used a height of 14in. To get the length, measure around the largest part of your belly, then subtract 2-4in depending on how snug you want it! If you are barely showing, or not showing yet, use your hip measurement and then subtract the 2-4in, you’ll grow into it! Happy belly banding!

  16. Hey this is just what i needed! i bought jeans which are SO LOW in waist and i need something to cover my *behinds* LOL

  17. Nessa said

    Thank you very much for this tutorial! I can’t wait to make some one my own for myself and friends for christmas! I have a Japanese friend who first introduced me to them by showin me hers and asking if we sold anything like this in Canada. I had to tell her that we don’t. But I loved the idea, so I decided to look it up online. I am very happy to have found you simple, yet wonderful tuitorial! I can’t wait to make one or two for her and surprise her on Christmas! Thank you so much!!!

  18. Susan said

    I loved these for maternity….but Lord, I am so very tired of seeing bellies between the jeans and shirts…either pull up the jeans or pull down the shirts. I have two sons who are the perfect age to ‘appreciate’ this style and they cannot stand it. Both sons love women, but they are quite picky….my oldest daughter has the perfect figure for the low cut and short shirts…but she won’t wear them…

  19. Molly said

    Hi! Like a lot of the other commenters, I wore a band like this during the early part of my pregnancy. I could only afford to buy one, though, because they were so pricy! Most of the time I didn’t like how it stuck out of the bottom of my shirt with such contrast (it was white). Maybe if I think of it as an under shirt sticking out it won’t bother me so much? I would love to see some more pictures as well. The one you made looks great! Thanks!

  20. Miriam said

    Hi! Just a quick tip – I made maternity bands out of this as well, but I just used cotton ribbing – it comes in a tube already and if you are skinny-ish you don’ have to fuss with it – I wear a size 14 and I used these for my entire pregnancy! It is a great tutorial and a wonderful idea.. I’d lvoe to see some pictures of a detailed/designed one!

  21. Tamara Watson said

    Thanks for the tutorial. I’ve got a maternity “belly band” that I still wear everyday because it is so comfy and its great for nursing (it hides my less than stellar belly when I pull up my shirt to nurse). I would love to have more, I can’t wait to try making my own!

  22. Jen said

    Thank you for this great tutorial! I too was searching for a pattern to make a maternity “belly band.” For $7 worth of fabric, I made something that seems to be just as functional as the ones you can buy for $20 or more! I’ve been wearing it around the house with my regular jeans, unbuttoned and unzipped, and it’s holding them up very comfortably! ๐Ÿ™‚ Thank you for sharing!!

  23. June said

    Lori, I use regular (polyester) thread. The key is in the stitch you use to sew it – if your sewing machine has a stretch stitch, you can use that, otherwise you can use a medium zig zag stitch. Close together, long zig-zag stitches will give the most stretch.

  24. Lori said

    Thanks for the great directions!! I just finished making my first one and I can’t wait to do more!! I think I will do the angel next time though.

    May I ask what type of thread you used? I just used regular and I could hear stitches popping when I stretched it.

    Thanks again!!


  25. Andrea said

    This is a great idea! My shirts are never long enough to cover all I’d like, especially in the winter. I will definately be making some of these for myself.

  26. Cassandra said

    I absolutely adore this idea! I’ll be making some very soon.

  27. Stephanie said

    This is fantastic! I’ve already made myself two and am making one for my daughter.. (she’s long waisted and has trouble finding shirts long enough to cover.. ) Thank you for posting this!

  28. Amber said

    I wear JUST the band and I get comments ALL THE TIME! Thank you for an amazing tutorial ๐Ÿ˜‰

  29. margie said

    Thanks for all the great ideas on tummy wraps. I’m wondering if anyone has any ideas/info about a wrap for the lower back/kidney area? I would like to make some warm wooly ones, either knitted, felted, or some combination of mediums and fibres. I am a fibre artist, and I am always cold in the winter. I find wearing an undershirt all the times helps tremendously, but sometimes I would like just a little more insulation in the lower back/kidney area. I would like to make some for myself, and possibly for sale.
    Thanks for the forum!

  30. Frankie said

    Oh, you really are the greatest. Thanx a million.

  31. June said

    Dana, I think the method would be the same – you’d obviously have to make the size a little larger to accommodate your bump! A finished height of 8 inches would clearly not be enough coverage – I would advise at least 12″ or more to cover the tummy comfortably.

    Try wrapping the fabric around your middle and see where it feels comfortable – it needs to be stretched a little when you wear it so it will stay up, but you also want to make it large enough to still fit you as you continue to expand! I see that website sells 2 sizes – I think you would probably need 2 or 3 homemade sizes to fit through your entire pregnancy.

    Also, remember to pick a fabric with stretch! If the fabric only stretches in one direction, make sure that’s the direction that goes around the belly (the “length” of your belly band), not the height.

    Hope this helps! I’d love to see the finished result ๐Ÿ™‚

    (PS – I’ve just realised, I am assuming you are the expectant mother here – sorry if this is for a friend and I’ve referred to “your” tummy all the way through!)

  32. Dana said

    Hi, the big trend in maternity clothes right now is “belly bands” it’s exactly what you have made. Just wondering if you have any suggestions to make one that would fit an “expanding” tummy?
    Here’s a website with them selling for $30….come on, I should be able to make one and that’s what I’m hoping to do. Yours is the only pattern I’ve found so far.
    Any tips/advice?

  33. Michelle taylor said

    Hello! I was wondering if I could use this tutorial on my website? I’d be more than happy to credit you in whatever way you desire, to whatever page you wish me to.

    I have a fansite devoted to someone that wears a haramaki and I’d be very grateful if you would allow us to use your lovely tutorial so that more fans that want to make this piece of clothing can find it. It’s the best one I’ve come across so far!

    And also, thank you for posting it on the internet :3

  34. Harrison said

    Haramaki’s have been around for a long time. If you really want to see great designs then you should look at the early 1920-70’s japanese movies. Those guys really look tough in their school black pants and kick @$$ Haramaki. But for real convience some of them even sported a pocket so such things as combs could be put in to keep the every fashionable hair-do in check.

  35. Ellen said

    Super idea.

  36. Miss "B" said

    Thanks so much for that great tute! I only discovered the Tummy Warmer yesterday and went to sleep thinking about having one to sleep in, one to exercise in, and a few to wear just anytime. I work with little children and now I won’t have to keep pulling on my t-shirt everytime I bend down or get on the floor with them. Thanks again for making my goal much easier.

  37. Amanda said

    Great idea! I actually wore something similar when pregnant this past time (had a baby in Feb.) to help hold up pants and fill in for too short shirts. I have still been wearing it to hide that plumber’s crack. Nice to see a tutorial for them!

  38. Tinkergirl said

    I did the angle thing at step 9, just as you thought. Took about an inch in at the ‘top’ of the seam, which worked out as 2″ shorter when unfolded, but I still could have done with a bit more. Still – if it hand’t been for you posting this, I’d never have tried it, and if I’d tried to buy one, there’s no way it would have fitted! Thank you so much.

  39. June said

    Tinkergirl, yes, my fabric was fairly stretchy. I wrapped it around my waist after step 4 (remember: 1/2 inch of seam allowance at each end, so there should be 1 inch of overlap when you wrap it around yourself) and then figured out if my tube was the right size. It looked like it may be a bit big around the waist, so I trimmed the length down a bit at that point.

    If you have a big difference between your waist and hip measurements, your haramaki could benefit from being sewn up at an angle (in step 9) so it’s smaller at the top than at the bottom. I just wanted to keep the tutorial simple! There’s plenty of room for customization to make it fit your own body and style ๐Ÿ™‚

  40. Tinkergirl said

    I just finished making mine – however I needed to put a bit of an angle on it, or it gaped pretty badly at the waist. Could be the fabric I chose wasn’t as stretchy as yours though. Thanks for posting the tutorial though – I’ll be making loads more!

  41. Jess said

    Hi! Thanks so much for this! Here in New Zealand they have been popular for the last few years. I have objected to the $20 (!!!) price tag!!! The other benefit is, you don’t get a peek at your *builder’s crack* every time you bend down!

  42. blufaerie said

    This is such a fantastic idea. I never liked low rise jeans for just that reason. Now I can wear them. And also, I can let my daughter wear them without worrying about her showing too much, lol.

  43. katrin said

    Yes, they’re so nice and cozy!
    The hubby wears a similar one when he’s out in the woods and I have one for skiiing, but I didn’t recognize how stylish and “fashionista-like” those can be – Thanks for bringing this up!

  44. gizmogal said

    finally! i’ve been looking for how to make one, since getting a real one seems near impossible in the US. D’:
    thanks so much!

  45. Sรธren said

    I’m so excited to make these! I’ve been wearing super long men’s undershirts to cover that gap, but they’re always white and a lot of the time the straps stick out the top and annoy me – this is so cool! Thanks!

  46. Katrina said

    Wow, thank you so much for this! I’m definitely going to have to try to make one. Ever since I saw that post I’ve been trying to figure out how to go about making one myself too. =D

  47. lisa said

    i’ve been planning to knit some–amazed that it’s taken us all this long to figure this out, for just the reason you said: i hate that cold part between my jeans and my shirts! thanks for the tute!

  48. Sharakh said

    Fabulous! I was planning to try a version myself this weekend, but you’ve already done the hard thinky bits for me. Thank you!

  49. Christine said

    Very clever, going to the top of my “must make” list!

  50. Allison said

    Love it! No more ‘muffin top’! ๐Ÿ™‚
