All seam allowances are 5/8 inch unless otherwise stated.

Getting Started

Start by cutting out and assembling your pattern pieces based on the size you’re making. Pin the pattern pieces to your fabric, and cut them out. Don’t forget to mark your notches!

Attach the Neck and Leg Bands

Pin the neckbands and leg bands to the neckline and leg openings, matching the ends of the bands to the edges of the pattern pieces. Stretch the bands to fit along the curves and pin.

Sew the bands to the front and back pieces with a 1/4 inch seam allowance. We’re using the Overlock stitch on our BERNINA B350, but using a serger or even a simple zig-zag stitch on your sewing machine are other great finishing options!

Fold the band over the seam allowance and pin, taking care not to fold the seam allowance. Next, secure the band by topstitching along the seam, or “stitch-in-the-ditch”, making sure to catch the loose end of the band from underneath. We’re using the SuperStretch stitch on our Bernina B350. However, using a Cover Stitch machine, a lightning bolt stitch (perfect for stretch fabrics) or simple zig-zag stitch will work as well! This will create a binding around the neckline and leg openings.

Attaching the Shoulders and Sleeves

With both right sides up and the necklines facing each other, place the Bodysuit Back over the Bodysuit Front, matching the shoulder notches, and pin in place.

Then, pin the sleeve section you just layered together to the arm opening, right sides together, matching all notches. Sew the sleeves to the arm openings with a 5/8 inch seam allowance.

Fold the bottoms of the sleeves up 1/4 inch and another 1/4 inch. Stitch to secure cuff.

Attach the Sides

With right sides together, match the notches and underarm seams and pin in place. Stitch along the sides from the sleeve cuff to the leg bands. We’re using the Overlock stitch on our Bernina B350; but just like the previous finishing, you can use a serger or even a simple zig-zag stitch on your sewing machine.

Add the Snaps

Fold the bottom of the Bodysuit Front at the fold line. Secure by sewing a line 3/4 inch from the fold. Attach the snaps to front and back pieces following the manufacturer’s instructions. 

Pro tip: Make sure to place your snaps on top of the marks you made in the first step.

    Hi, Thank you very much for this cute pattern. its very easy to understand. I am a fashion designer not a pattern maker. But I love to create bodysuits. So this is very helpful to me.. thank you so much. and, if you can upload a sleepy suit as well it will be great.. 🙂

  • question clarification:
    The fabric stretches parallel to the center fold so I should place the pattern front, back,…so it stretches around the belly which is perpendicular to the center fold line. That means I would not fold the fabric where the fabric line is but open the fabric up and fold it the other way so the material\’s fold line is folded on top of itself.

    • Hi Georgia,

      When cutting out all your baby bodysuit pieces, position them so the stretch goes around the body just like you said. The fold line only indicates that the pattern piece should be placed on a folded edge of your fabric before cutting, not that it needs to be cut in that exact orientation. So, you’re correct that you would fold the other way to achieve maximum stretchiness!

      The arrow on the front leg band pattern piece is known as the “grainline.” This particular grainline should go on the non-stretch direction of your fabric, resulting in a piece that is stretchier from side to side rather than up and down. This will allow the leg hole of the final bodysuit to have as much stretch as possible.

      Happy sewing!

  • I’m new to sewing with stretch material and I’m not quite sure the layout. Is there a photo of how best to lay it out? I’m making the baby bodysuit from organic cotton knit. What I have read is you cut the pattern out so the stretch goes around the body. The stretch does not go from head to toe. Is that true for this baby bodysuit also or does it matter? The fabric stretches parallel to the center fold so should I place the pattern front, back, neck and leg pieces so it stretches around the belly which is perpendicular to the center fold?
    Also, there is a front leg band with an arrow stretching across the narrow bottom of the piece. Does the arrow go the direction of the stretch or the non stretch direction? (The non stretch direction stretches a bit but not like the stretchy direction.)

    Hi,

    Thank you for making this. *multi sized* pattern so easy to find and download. I’m so tired of spending hours on pinterest trying to navigate through endless links, and registering.

  • Too frustrating to even finish. I’m not a beginner, I sewed my own wedding dress, I’ve made costumes for plays, and I’ve sewed all sorts of work clothes for myself. The sleeves on this made me give up on it. Do yourself a favor if you’re thinking about making this and just buy something cute from a local shop.

    • Hi there,

      We have updated this tutorial to make it a bit clearer, hope that helps!

  • Hi

    Thank you very much for this beautifull free pattern….just want to know must this be printed out on A4 paper

    • Hi Erna,

      Thanks for your interest! All of our patterns are made to be printed on standard printer paper which is 8.5 X 11 inches. I hope this helps, but please let us know if you have any further questions!

      Take care,

  • I just finished up my first bodysuit, and it is so adorable! The only issue is the snaps – I tore a hole in the fabric trying to get them apart for the first time. I’d suggest adding interfacing or doubling up the fabric for the snaps attached to the back body piece, where there is just one layer of fabric. The snaps on the front body piece seem to be fine since the fabric is doubled there. Thanks for the great pattern!

    • Hello! I noticed that for the long sleeve version, the length is not graded for different sizing. I am pretty sure newborns and 12-18 month babies have different length arms. Did I miss something with the pattern?

      • Hi Shayna,

        Thank you for your feedback! We have updated the pattern to include grading for the long sleeves.

        Take care,

    • Hi Emma,

      Thanks for sharing this helpful tip and we’re so glad you enjoyed the pattern!

  • Hello,
    Thank you for the wonderful pattern! It looks like you’ve mentioned this in the comments a few times, but I just downloaded the pattern and I’m not seeing the notch for lining up the overlapping front and back shoulder pieces. There is just the one notch in the arm hole area for lining up the sleeve, but this seems to be different from a notch that would be used for lining up the front/back. Thanks!

    • I\’m new to sewing with stretchy material. I\’m glad you put the comment about stretching the bands to fit around the curves. there was a lot of stretching going on but it worked. When I sewed the bands on I was not sure to sew with the band side up so I could see the band while sewing it on or the or the bodysuit side up. What would you advise? Also, when sewing the side seams up starting from the arm ( good to know which end to start sewing) what do you do with the seam around the armhole? Do you open the underarm three layer seam like you would a dress armhole with two layers sewn to one side and one layer on the other side to flatten out the seam
      or sew all three layers of the underarm seam up or down flat to one side of the bodysuit when sewing the side seam?

      • Oops it’s only two layers of fabric under the armhole. Still do you open up the seam flat or sew the two underarm seams toward the mid line or towards the sleeve? Maybe it does not matter.

        • Hi Georgia,

          We recommend opening this seam flat for a cleaner finish, but ultimately you can press it in any direction and it will work fine. In regards to your last comment, sewing the bands band-side-up would be ideal so you can make sure the stitch on the outside is neat.

          Happy sewing!

  • Ingrid van peufflik

    Is the seam allowens already included in the pattern, Or should I draw the seams myself?

    Also in the Netherlands, we use a different size notation. Instead of months, we use measurements like 50, 56, ect.
    the one which size would then be from 3 – 6 months?

    • Hi Ingrid,

      Yes, the seam allowances are included in the pattern and the seam allowance is 5/8″ unless otherwise stated within the written instructions. We hope to have an answer to your other questions soon.

      I hope that helps, but if you have any more questions don’t hesitate to ask!

  • Good afternoon from Spain, I love your project to make a baby bodysuit but I have a question: are the seam allowances included in the pattern? that is, should I cut the pattern just by the line of my size or should I leave a margin when cutting the fabric?

    Thank you very much and sorry for my English;)

    • Hi Moni,

      The 5/8″ seam allowances are included in the pattern so you should cut directly on the line of your selected size.

      I hope that helps, but if you have any more questions don’t hesitate to ask!

      Best Regards,

  • Hi, thank you for this pattern, i was really nervous about trying this, but this pattern seems to easy I am giving it a try!
    The one part I am confused about is attaching the sleeves. There are no photos, and not even a glimps of the sleeves pinned onto the pattern and I am not sure how this should be done. Can you maybe add a photo of the sleeve pinned to the body before sewing? How am I supposed to lay this piece on? Should I sew the arm opening first?

    Thank you again for the pattern!

    • Hi Jules,

      You can certainly baste the front and back arm openings together first if you prefer! Regardless of whether this is basted or simply pinned, you will lay the sleeve piece face down on top of the arm openings, matching the notches. When pinning the sleeve to the arm opening, the curved edges of the sleeve will be pinned to the edges of the arm opening, with the sleeve hem (straight edge) pointed towards the opposite side of the body suit.

      I hope that helps, but if you have any more questions don’t hesitate to ask!

    • Hi Priyanka,

      Thanks for your question! This pattern is intended to be printed on a 8.5″ x 11″ piece of paper.

  • On the “Sleeve Cut two” cut out I am a bit confused. There are horizontal lines for the sizing cut, but then there’s diamonds parallel with the dotted lines. How do I cut this? Do I cut off the diamonds?

    • Hi Rayanna,

      The diamonds are meant to aid in matching up the two pieces of the sleeve pattern if you wish to create a long-sleeved bodysuit. If you wish to create a short-sleeved bodysuit, you will not need this portion of the pattern!

      I hope that helps, but if you have any more questions don’t hesitate to ask!

      Best Regards,

  • Thank you for a great pattern and tutorial. Although, I downloaded the pattern and still cant see the notches and if the notches are the small ones they dont seem to match when I try to put them together. I am doing the 3-6 month one. Also, the tutorial is not clear in reference to the sleeve part. Can you please give me a clear direction on this part? I cant seem to understand with the video or written instructions. Maybe a picture instruction just for the sleeves perhaps. Thanks again great blog.

    • Hi Deborah,
      Thanks so much for your question and we apologize for the unexpected issues. Are you able to confirm if the pattern was printed 100% to scale? This should help ensure the ntoches line up correctly.

      For the sleeves, you will lay the sleeve piece face down on top of the arm openings, matching the notches. When pinning the sleeve to the arm opening, the curved edges of the sleeve will be pinned to the edges of the arm opening, with the sleeve hem (straight edge) pointed towards the opposite side of the body suit.

      I hope that helps, but if you have any more questions don’t hesitate to ask!

  • Does this require a 4-way stretch knit fabric? Or is cotton knit with 2-way stretch sufficient?

    • Hi Meli,
      Great question. Our patternmaker let us know that the newborn size is equivalent to 0-3 months. We’ll make an update in the pattern!
      Best,
      Suz from Spoonflower

  • Love this pattern and project; thank you! I\’m a bit confused about the neck/leg bindings. I\’m trying to finish the bindings with a zigzag, but is it a topstitch that you can see from the front? A more contrasting thread color with few more slow, closeup shots of that part of the project would have helped a ton. I can\’t really see what\’s going on.

    • Hi Kait,
      Thanks for your question, and sorry for any confusion! You’re correct that the bindings are secured with a topstitch. We used a lighting bolt stitch – it’s good for stretch fabrics, but looks slightly more like a straight stitch. We’ll update the post to clarify!
      Best,
      Suz from Spoonflower

  • Hello! This pattern and tutorial is great 🙂 Thanks a lot for sharing this on your blog. I made one piece for my daughter using old T-shirt and yellow fabric from my recources. Because I love some girlish accessories, I just added small bows on the front and frills on sleeves 🙂 I shared about this on my blog. Regards from Poland!

    • Hi Ania,
      Your version turned out great and we love how you made it your own sustainably! Thanks so much for sharing.

    • Hi Kira,

      This pattern is specifically intended for a stretchy, knit fabric. If you’d like to use a woven fabric like flannel, you may want to work with a pattern that requires woven fabric to ensure the bodysuit fits. I hope that helps, but if you have any more questions don’t hesitate to ask!

  • I’m hoping to make a short-sleeved bodysuit, but I’m confused because your photo shows 3 short-sleeved ones but your adorable little model is wearing a long-sleeved one? I don’t see anything in the written instructions about this. I’ve just printed the pattern and there’s the “Sleeve” piece and also the “Sleeve B” piece. Is one of these the short sleeve and the other the long?

    Thank you!

    • Hi Dee,

      If you would like to make a short sleeved version, you can omit attaching Sleeve B to your pattern. You’ll notice in the image below the section Getting Started, both sleeve pattern pieces are attached to create a long sleeve bodysuit. I hope that helps, but if you have any more questions don’t hesitate to ask!

  • Hi, I’m having an issue with the shoulder notches. My pattern unlike the one in the video only has one notch and I can’t make them match up. Could you advise please?

    • Hi Chrissy,

      We’re so sorry for the trouble! The pattern has been updated to include notches for both matching the midpoints of the arm openings on the front and back pieces, as well as matching the sleeve to the arm openings. We would recommend downloading the updated version of the pattern here.

      I hope that helps, but if you have any more questions don’t hesitate to ask!

  • I\’m a little unsure at it seems as though the notches in the video/picture tutorial are a lot higher than the ones one the pattern? Which should I be following

    • Hi Anna,

      Thanks so much for your question! We’ve updated the pattern to include the notches at the top of the shoulder as seen in the video tutorial. I hope that helps, but if you have any more questions don’t hesitate to ask!

      • Hi, you state that you updated the pattern to include the notches, but the one currently available to download does not show them. Am I just obtuse? I\’m assembling the item and just rechecked your download. No upper notches shown.

  • Thank you for the tutorial, a little step by step is always heldful! 🙂
    I have some questions though:

    1. You don\’t cut with seam allowance for the leg- and neckbands in the picture, does that mean the seam allowance is already included in the pattern pieces in general? Or just in the band pieces?
    2. I\’m supposed to sew the band with 1/4 seam allowance. In the picture it looks like you sew so that 1/4 inch seam allowance remains? Is that the way to go?

    Maybe you can help me out, I unfortunately do not have a baby that can try the body on, otherwise I would just sew and see how it fits, but it\’s supposed to be a present 😉

    Thank you
    Jess

    • Hi Jess,
      MaryAshlyn used a 1/4″ seam allowance when sewing the bands. Once those seam allowances are sewn, you should just fold the rest of the band back over the edge and stitch. I hope that helps, but if you have any more questions don’t hesitate to ask! – Meredith

    • Hi Alicia,

      We hope the following information will help provide clarity for this step: lay the sleeve piece face down on top of the arm openings, matching the notches. When pinning the sleeve to the arm opening, the curved edges of the sleeve will be pinned to the edges of the arm opening, with the sleeve hem (straight edge) pointed towards the opposite side of the body suit.

      I hope that helps, but if you have any more questions don’t hesitate to ask!

  • Sheila McCormick

    First of all, thank you so much for all of the fabulous work you put into this pattern. It’s the first one of yours I’ve tried. However, I printed the pattern to make the largest size. Cut it out and tried to put it together. There were no notches for the overlapping of the neckline pieces. I thought I had figured it out and sewed it together but the back is 3.5 inches shorter than the front. I’ve double checked the pattern pieces and that is correct. Is there a flaw or have I done something wrong?

    • Hi Sheila,

      We’re so sorry to hear about the unexpected issue. We have updated the pattern to include the additional notches but if you continue to have trouble, please do let us know.

  • Well, for starter’s, I don’t have a zigzag sticth on my machine. I’m using a 1940 singer machine. I did throw in a stay stitch around the parts for the bias to try to keep it flat as possible and tried not to stretch the knit to much so it wouldn’t create puckers. The directions weren’t really clear on the shoulders and arms sleeves. I don’t know where I’m to begin and end with my stitch and would there be any bulk to cut off. Your directions make it sound like I’m to pin both front, back, and arm sleeve’s together and then sew all 3 together. Sleeve’s are the most difficult for me, and I’m not sure I want to chance sewing all 3 at once, especially on knit. This is my first knit fabric project, and I really don’t want to be ripping stitches out if I don’t have to. Also, what size snaps are to be used. So far my little onesie is taking off, and I do thank you so much for sharing your pattern and taking the time to teach all of us how to make one. You are a true blessing!

    • I’m using my Mom’s 1959 Singer, works like a champ. I appreciate reading your comment, gives me some perspective. I almost want to buy a fancy new matching that does everything for you! LOL

    • Hi Shirley,

      We’re sorry to hear the instructions were unclear and we are working to improve the clarity.

      For snaps, using your preferred type is fine. We’ve used size 1 sew-in snaps (Dritz), size 20 KAM-style snaps, and size 16 metal snap fasteners (also Dritz). All three have worked great, but our favorite so far has been the KAM-style. If you’re looking for something they won’t need a specific tool to attach, sew-in snaps are perfect. -Meredith from Spoonflower

  • Amanda Meloni

    Cute onesie. Except I’m in the middle of making it. Attaching back to front am holes. There’s only one notch on each arm opening. Impossible to match up. My pattern does not look the same (notches) as yours in the photos. I am new at sewing, but my pattern is not matching up. Very frustrating. I’ve spent so much time sewing the neck line and leg openings. Now I might not be able to piece this together properly at all.

    • Hi Amanda,

      We’re so sorry for the trouble and frustration! The pattern has been updated to include notches for both matching the midpoints of the arm openings on the front and back pieces, as well as matching the sleeve to the arm openings. We would recommend downloading the updated version of the pattern, here.
