Is your baby ready to be a trendy hipster, geeky nerd, or chic preppy? Choose your baby’s style with the new cardigan onesie style. Just take a long-sleeved onesie make a couple of snips and additions, and it’s a whole new style. I’ll tell you how to do it in this simple baby cardigan onesie tutorial. I have updated and simplified this tutorial! You can see the new cardigan onesie tutorial or keep reading!
There are lots of fun details about this cardigan even though it’s fairly simple to make. It’s so fun to mix and match the colors and buttons.
It can be worn with or without pants or a skirt. It would be fun paired with a collared shirt, suspenders, and a bow tie. I would love to see it with a skirt and knee high socks for a little girl!
Update: I’ve had a lot of people have problems with the knit band or ask questions about it. The reason you multiply by .8 is so that the band does not gap or stretch out. When you cut the onesie and then sew a seam, it will stretch. By using a slightly smaller band, it will counter the stretching out and make it lay nicely. Also, use RIBBING and preferably with spandex to make your life a lot easier.
Supplies
- Long or short sleeved onesie- (I think the short sleeved ones look best on girls.)
- RIBBING (make your life easier by using ribbing with spandex!)
- Buttons or snaps
- Sewing tools and sewing machine
- Find the updated cardigan onesie tutorial here!
- Tips for sewing knit fabric
Instructions
- If your onesie has crossover shoulders, find where the crossover lays flat and pin two layers together.
- Sew with a straight stitch the two layers together so they don’t come apart.
- Measure across the front of the onesie and mark the center all the way down. At the bottom slant to one side between two of the snaps.
- Cut on the line.
- Draw from shoulders to parallel with the armpits.
- Cut on lines up around the neckline so that you cut off the neck band.
- This is perfect if there’s a small picture, phrase, or stain near the neckline that you want to get rid of.
- This is perfect if there’s a small picture, phrase, or stain near the neckline that you want to get rid of.
- Measure the whole length of the cut edge. Take the measurement and multiply by .8. Add 1/4″ seam allowance. This is the length of the front band. I wanted my band to be 3/4″ tall, so double that amount and add 1/4″ seam allowance. Make sure the stretch goes with the long sides.
- Sew ends at 1/4″.
- Turn right side out and poke out corners.
- Find the center of the band and then the center of each side, so you divide the band into four sections. Use the same method to divide the cut edge of the onesie into four sections. Match pins.
- Stretch each section and pin so the excess is distributed evenly.
- Stretch while zigzagging at 1/4″.
- Zigzag the edges of the snap facing to prevent fraying.
- With your machine set on to a straight stitch, stretch and sew the seam allowance towards the onesie. Sew at 1/8″. Careful when going over the shoulders.
- Snap the snaps together overlapping the two sides.
- Pin the two layers together and sew together.
- Pin two layers of the front band together at three or four places. Sew buttons on at each pin.
Optional
- Cut off sleeve hems. Measure length.
- Take the measurement and multiply by .8. Add 1/4″ seam allowance. Use the same height as the front band.
- Sew short edges to make a tube. Fold in half with right sides out.
- Sew band to each sleeve end at 1/4″ stretching to fit.
- With a straight stitch, stretch and sew the seam allowance towards the sleeve at 1/8″.
These baby boys are off to college in their new cardigan onesies.

May 2, 2014 at 3:30 pmI love this idea!! Do you think you could use snaps instead of buttons and button holes?
Heather Feather says
May 5, 2014 at 3:46 pmYou definitely could!

March 22, 2014 at 5:16 pmThis is awesome!i can't wait to make an old man cardigan out of a onesie for my oversized 1 month old boy! I've just pinned this and someone posted a pic of their own version in the peek a boo patterns Facebook group.

July 7, 2013 at 2:21 amLol.. I saw this on Pinterest and I was like isn't that so-and-so's baby? Then I saw the background of the photos 🙂 we used to live in the 800 court 🙂

March 8, 2013 at 8:32 pmDo you mind my asking where you found the ribbing? I've looked at all the local fabric stores and can't find anything similar.
Heather Feather says
March 9, 2013 at 2:49 pmI know joann's definitely has rib knit. Hancock's doesn't. You'd be able to find rib knit most places online. You could even buy used sweatshirts to use the ribbing from the hem and the sleeves.
Nancy Blumberg says
August 8, 2014 at 11:02 pmI could NOT get the rib knit at Joann's in Nashville TN> I had to go to a speciality store!!

February 5, 2013 at 6:36 pmI am getting ready to make this for a friend, and I just wanted double check, the buttons are not actually functional correct?
Heather Feather says
February 5, 2013 at 7:47 pmThat's right! They aren't needed!
Baby OZ Clothing says
January 30, 2013 at 4:18 amI found that if I multiple the measurement by .80 works better than the .75. Too much puckering when I use good rib knit. I also have a tool that takes off the snap and my husband straightens the prong out so I can reuse it, so I cut it straight down. I didn't like the angle cut especially on the smaller sizes.

January 26, 2013 at 10:25 pmI am interested in making these to sell. I don't want to steal your idea or anything so am asking permission. I will be using this tutorial (http://dieselinbloom.blogspot.com/2012_09_01_archive.html) in addition to yours but wanted to check with you as far the the permission to use parts of your tutorial to make my items. I see you have given another etsy store permission to sell also. Thanks so much!

LOVE this tutorial!! Just made my first one last night and your tutorial was great! Question though, I had a really hard time with the border and getting my knit to stretch enough (it worked, was just SUPER difficult to stretch and feed and sew straight), so I'm wondering what would happen if I didn't multiply by .75? THANKS!!
Heather Feather says
November 21, 2012 at 2:23 pmYay! I'm so glad you made one! I've had a lot of people asking about the knit and having problems with it. The reason that the band is smaller than the body piece is because if it's the same length, the seam will stretch out the area and the band will gap. All knit cardigans do this even though you can't see it.
It will be a lot easier to use ribbing because it stretches well without shrinking. Or multiply by .85 instead.
I hope that helps!

September 21, 2012 at 3:29 pmHey Heather, I'm about to try to make one this weekend! I have a question, and it may seem stupid, but still. Where did you get the knit fabric for cuffs and border? Joanns? I've never bought knit fabric before. Thanks!

Abby says
August 27, 2012 at 1:31 amDid you multiple by the .75 for the orange and gray cardigans too? They don't look gathered like the gray striped one but it could be because the boys are wearing them. Love the tutorial and can't wait to make some for my little guy. Thanks so much!
Heather Feather says
August 27, 2012 at 7:48 pmI did multiply by .75 for the orange and gray cardigans you just can't see it while the boys are wearing it because the fabric gets stretched out.
