Little babies are so fun to sew for. They look so cute in anything you make with their soft skin and sweet smiles. My favorite way to sew for babies is to refashion or upcycle something. That way I can fit in a small project between all their baby needs.

I’m excited that I’ve redone my original and popular cardigan onesie tutorial. The pictures needed updating since the original is 4 years old, and those little babies have grown up. Now I have a cute little baby girl to photograph wearing a cardigan onesie!

I made this version way simpler so it’s easier and quicker to make. (You can also try the simplest and easiest cardigan onesie.) This is a girly version, but I love that cardigan onesies work well for both boys and girls. I can’t wait to pair this cardigan onesie with a little skirt and knee high socks.

I also added a cardigan onesie tutorial video to the end!

SUPPLIES

INSTRUCTIONS

  1. Sew the overlapping shoulders together so that they aren’t separate. I sewed mine with a straight stitch since this part doesn’t need to stretch. I sewed my straight stitch one top of the original stitching so you wouldn’t see it.Cardigan Onesie Tutorial: UPDATED // heatherhandmade.com
  2. Cut the edge of the neckline off and cut a v-neck. Cut straight down the center front with a little detour between two of the snaps at the bottom. Cardigan Onesie Tutorial: UPDATED // heatherhandmade.com
  3. Measure the total length of the edges you just cut. If you are using a ribbing with 50% stretch and good recovery multiply the length by 80%. If using ribbing with more than 50% stretch and less recovery multiply the length by 75% or less. Cut this long length with the long side going with the stretch of the ribbing. The height of the ribbing should be between 2″.
    4. Fold the ribbing right sides together and lengthwise. Sew the short edges together at 1/4″. Trim the corner. Turn right side out. Do the same to the other short end.Cardigan Onesie Tutorial: UPDATED // heatherhandmade.com
  4. Fold the ribbing in half lengthwise. Pin the center of the ribbing to the center back of the neckline. Pin the finished ends of the ribbing to the bottom edge of the onesie near the snaps. Dividing each piece in sections, stretch and pin all along the edge.
  5. Sew the ribbing to the onesie with a zigzag stitch. Carefully stretch the ribbing to fit the onesie but don’t stretch the onesie while sewing.
    8. Finish the edges with a serger or zigzag stitch. Press well.Cardigan Onesie Tutorial: UPDATED // heatherhandmade.com
  6. Sew the seam allowance towards the body of the onesie with a straight topstitch.Cardigan Onesie Tutorial: UPDATED // heatherhandmade.com

10. Add snaps or buttons depending on the look you’re going for to close the front like a cardigan. You’re done!Cardigan Onesie Tutorial: UPDATED // heatherhandmade.com
