How to Make a Pregnancy Pillow Step by Step

How to Make a Pregnancy Pillow Step by Step

A pregnancy pillow runs anywhere from forty to well over a hundred dollars, and most of the tutorials showing you how to make one assume you own a sewing machine and already know what a serger is. That's a pretty big assumption for someone who's just tired and trying to sleep.

So here's the deal: there are three real ways to end up with a supportive pillow, and only one of them needs a machine. Pick the route that matches what's already in your house, and you'll be propped up comfortably tonight instead of waiting on a delivery.

Decide Which Build You're Doing: Sewn From a Pattern, Gut-and-Restuff, or No-Sew

Sewn from a pattern. You get the best shape and the best fit, and it's the only route that lets you choose your own fabric. It's the most work. You need a machine, thread, and a few hours. A serger is nice to have but not required — I'll flag every step where people assume you have one, because you don't need it.

Gut-and-restuff. This one starts with a body pillow you already own, even a flat, sad one. You open a seam, pull the old filling out, reshape the case into a C or U, restuff it, and close it back up. The numbered walkthroughs floating around online follow roughly this order: measure, rip the seam and gut the pillow, mark and pin, follow the lines, stuff, then pin it shut. What they skip is sizing and firmness, which is honestly the whole game.

No-sew. A zippered body pillow cover plus a bag of loose fiberfill. Zero equipment, under half an hour, and usually under thirty dollars total. If you're reading this with a baby kicking you in the ribs at 2 a.m., start here.

Measure Yourself and Your Bed Before You Cut Anything

Measure Yourself and Your Bed Before You Cut Anything

Skip this part and you'll end up with a pillow that's gorgeous and useless. Grab a tape measure.

Lie on your side, roughly where you sleep, and have someone measure from your shoulder down to your knee. That number is the straight run your pillow needs to cover. For most adults it lands somewhere between 50 and 60 inches.

Then measure your mattress width. A U-shaped pillow eats a lot of bed. On a full or double, two wide arms plus a partner rarely all fit — a C shape works better because it stays on your side.

Here are starting numbers you can steal:

  • C-shaped: about 60 inches long, 12 to 14 inches wide through the middle, tapering to 8 or 10 inches at the tips.
  • U-shaped: two arms around 50 to 55 inches, joined by a bottom curve roughly 24 to 30 inches across.
  • Belly wedge: about 12 by 16 inches.
  • Add 5/8 inch seam allowance on every edge if you're sewing, plus an extra inch or two of slack for stuffing. A pillow case that fits exactly with no room to spare will look like a sausage.

Choose Your Fabric and Stuffing (and Know What a Stretch Stitch Is For)

Choose Your Fabric and Stuffing (and Know What a Stretch Stitch Is For)

For fabric, plain woven cotton is your friend — quilting cotton, cotton flannel, or muslin. They're easy to cut, easy to sew, and hold up in the wash. Jersey knit is softer and stretches nicely around a bump, but it's fussier to work with. Avoid anything slick or satiny; it slides around and frustrates you.

Now, a stretch stitch — because every tutorial mentions it and none of them explain it. It's just a narrow zigzag. On a regular machine you set your zigzag width very small (around half a millimeter to one millimeter) and the length to about 2.5 to 3 millimeters. Why bother? A straight stitch has no give, so if the fabric stretches while you're using it, the thread snaps. A stretch stitch stretches with it. You only need this on knits. On woven cotton, a normal straight stitch is fine.

Do you need a serger? No. A serger trims and wraps a raw edge in one pass, which is fast and tidy. But you can finish edges just as well by zigzagging over them, cutting them with pinking shears, or sewing a French seam. Every step below tells you when the serger crowd does it differently.

For stuffing, polyester fiberfill is the practical pick — washable, springy, and easy to top up later. Shredded foam gives you a firmer, heavier pillow. Buckwheat hulls are firm and moldable, but heavy and noisy. Cotton batting packs down flat and goes lumpy fast.

Buy loose fill in a bag rather than a pre-made insert, so you control how firm it ends up. A full U-shape takes roughly 4 to 6 pounds, a C-shape 3 to 4 pounds, and a belly wedge about 2 pounds.

Step-by-Step: Sewing a U- or C-Shaped Pregnancy Pillow From a Pattern

This is squarely in advanced-beginner territory. If you've sewn a pillowcase, you can do this. If you've never touched a machine, the no-sew route further down will treat you better.

  1. Make your pattern. Tape together sheets of butcher paper or freezer paper. Fold it in half lengthwise, sketch half of your shape, cut, then unfold — you get a perfectly symmetrical C or U. This is effectively what a printable pattern gives you, and it fits your body instead of a stranger's. (Free pattern PDFs are out there if you'd rather download one, but drawing it takes ten minutes.)
  2. Cut two pieces from your fabric, both the same, adding 5/8 inch all the way around.
  3. Finish the two short ends of each piece. This is the serger step. With a serger, run each end through. Without one, fold the end over half an inch and top-stitch it down using that narrow zigzag stretch stitch. Either way you get a clean, non-fraying end that won't shed fluff all over your bed.
  4. Pin the pieces right sides together. Leave a 10 to 12 inch gap along one long edge for turning and stuffing. Mark the gap with two pins so you don't accidentally sew it shut.
  5. Sew with a 5/8 inch seam, backstitching at both ends of the gap so it doesn't unravel.
  6. Clip the curves. Snip little notches into the seam allowance around every bend. Skip this and the pillow won't lie flat when you turn it.
  7. Turn it right side out and push the curves out with a blunt pencil.
  8. Stuff it in small handfuls, pulling each clump apart as you go. Push filling into the tips first with a broom handle.
  9. Keep the top quarter slightly looser than the middle, so the ends cradle your shoulders and knees instead of shoving them.
  10. Close the gap with a hand-sewn ladder stitch — a simple stitch that hides the thread inside itself so you can't see the seam.

Step-by-Step: Converting an Old Body Pillow Into a Pregnancy Pillow

Got a body pillow that's gone flat? Don't toss it. You've already got a case, a zipper or seam, and free filling.

  1. Check the size. A standard body pillow is around 20 by 54 inches, which is a good starting point for a C shape.
  2. Mark your new outline on the pillow with tailor's chalk, right over the fabric.
  3. Open a seam. Use a seam ripper on one short end and make a 6 to 8 inch opening. No seam ripper? A small pair of scissors and patience works.
  4. Gut it. Pull the old filling out into a bin or a clean trash bag. Don't throw it away yet.
  5. Mark and pin. Pin along your chalk lines so nothing shifts while you sew.
  6. Follow the lines with a straight stitch, backstitching at both ends. Leave your opening as the way you'll restuff it.
  7. Trim the extra fabric down to about half an inch past the seam, then zigzag or pink the raw edge.
  8. Restuff. Mix the old filling with fresh fiberfill, roughly half and half, so it plumps back up. Old filling alone will go flat within a week.
  9. Pin or stitch the opening closed. If you're dead set against sewing, safety pins will hold, but they'll pop out eventually and jab you in the night. Stitching it takes five minutes by hand.

Step-by-Step: The No-Sew Version With a Blanket or Pillow Insert

No machine, no needle, no problem. Three honest options, easiest first.

Option one: the zippered cover. Buy a body-pillow cover with a zipper or an overlapping envelope flap — check before you buy, because plenty of covers have neither. Buy 4 to 6 pounds of loose fiberfill. Unzip, stuff in handfuls, work the fill into the ends with a wooden spoon, zip shut. Done. That's the whole build.

Option two: the blanket roll. This is the one the sewing community keeps recommending, and it costs nothing if your linen closet is already full.

  1. Take two throw blankets, or one thick fleece blanket and one thinner one.
  2. Fold them in half lengthwise and roll tightly into a long tube.
  3. Bend the tube into a C or U shape.
  4. Hold the ends in place with wide elastic headbands, hair ties, or a ribbon tied in a bow.
  5. Roll a smaller second tube for between your knees.

Option three: the tied fleece. Cut a length of fleece twice as long as you want the pillow, fold it in half, then cut fringe along the two open sides and tie the strips into knots — the same method as a no-sew fleece blanket. Leave the last edge open, stuff it, then knot that one closed too. Honest warning: tying takes about as long as sewing, and the knots make the edges lumpy. It's a real option, not the fastest one.

How to Make a Removable Pregnancy Pillow Cover You Can Wash

You will want to wash this thing. Body heat, sweat, and eventually spit-up all end up in the fabric.

The easiest washable cover is an envelope back, and it needs no zipper or buttons.

Cut two rectangles the length of your pillow's face. Make one of them 8 to 10 inches deeper than the other — that extra bit becomes the overlap that holds everything in. Hem the two short ends of each piece by folding over half an inch twice and stitching. Lay one piece right side up, lay your pillow on top, lay the second piece right side down, overlapping the first by those 8 to 10 inches. Pin, sew all the way around with a half-inch seam, clip the corners, turn, and slide the pillow in. The overlap keeps it shut.

Can't sew at all? A zippered pillowcase works for a straight body pillow, and two overlapping pillowcases do the same job in a pinch. A king-size pillowcase is a decent fit for a slim C shape.

Wash the cover weekly on a normal cycle. For the insert itself, spot clean and air it in the sun rather than wrestling a giant stuffed pillow into your machine — a home washer will wad fiberfill into hard clumps that never come back.

How Firm and How Big: Sizing and Stuffing So It Actually Supports You

This is the part nobody covers, and it's the difference between a pillow you love and a pillow you shove off the bed.

Stuffing rules of thumb:

  • Fill to about three-quarters full, then add one handful at a time.
  • Do the palm test. Press down with your flat hand. You want about an inch of give, then solid resistance underneath.
  • If it folds in half under its own weight, it's understuffed. Add more.
  • If it feels like a fence post, it's overstuffed — and a rock-hard pillow pushes your belly instead of supporting it.
  • Lumps come from shoving whole clumps in. Break every handful apart with your fingers as you go.

Sizing rules of thumb:

  • The straight run should reach from your shoulder to your knee.
  • U-shape arms should be 10 to 12 inches wide so you can actually hug one.
  • The bottom curve needs to be wide enough that your knees rest on it without sliding off.
  • A belly wedge should be small — 12 by 16 inches is plenty. Bigger isn't better here.

One thing worth saying: a cervical pillow is a completely different project. It's a smaller, firmer roll shaped for your neck, and the same fabric and stuffing supplies apply, but don't try to make one pillow do both jobs. Different shape, different firmness.

When to Start Using a Pregnancy Pillow, and What to Use Instead

When to Start Using a Pregnancy Pillow, and What to Use Instead

There's no official week. The trigger is comfort, not the calendar. Most people find side sleeping starts getting awkward somewhere in the second trimester, and that's when a pillow earns its place. If you're uncomfortable earlier, start earlier. If you're comfortable at 30 weeks, you don't need one.

One caveat: none of this is medical advice. If sleep is genuinely painful, or you're worried about how you're sleeping, ask your midwife or doctor. A DIY pillow is a comfort object, not a treatment.

What to use instead, if you'd rather not make or buy one:

  • A thin knee pillow between your knees, which keeps your hips level.
  • A rolled-up fluffy blanket — sewers swear by this one, both as knee support and something to cuddle.
  • Two ordinary pillows: one tucked under your belly, one behind your back.
  • A rolled towel under the bump, which is firmer than a blanket and stays put.
  • A folded duvet, if you want something big and soft without any structure.

All of these are free if they're already in your house.

After the Baby Arrives: Repurposing or Storing Your Pillow

After the Baby Arrives

Don't store it in the attic and forget about it. A pregnancy pillow keeps earning its keep.

A thin knee pillow works great after pregnancy, and a full-size one does fine as a bolster when you're sitting up in bed. It can support your back or your arm during feeds, and later it's a supervised tummy-time prop on the floor — flat, on the floor, with you right there. Never for sleep, for a baby or anyone else.

If you're packing it away, wash the cover, then vacuum-bag the insert and stash it somewhere dry and out of direct sun. Vacuum bags squash fiberfill flat, so shake the pillow out and let it breathe for a day before you use it again. And if it never worked for you, pass it along — these things resell fast.

While you're still in nursery-prep mode and the sewing machine is already out, it's worth sorting the next size up too. Baby Sock Shoe has first-shoe and sock-size guides that take the guesswork out of those early weeks, so you're not buying three sizes of everything and hoping one fits.
