What’s cuter than a baby wearing handmade leggings? A baby wearing handmade leggings with a coordinating handmade onesie! We’ve grown to love making clothes for the littles ones in our lives because they’re perfect stash busters and most projects can be easily made in under an hour. Using just one yard of your favorite knit fabric and our free pattern, you’ll be able to sew two onesies in no time! Bonus: these make great baby shower gifts!
- 1 yard of knit fabric like Modern Jersey, Organic Cotton Knit or Cotton Spandex Jersey
- Free downloadable Baby Onesie Pattern
- Available in sizes 0-18 months
- Scissors or rotary blade
- Sewing machine, we’re using our Bernina B350
Pro tip: Try this pattern as a Fill-A-Yard® project! You can make two (any size) onesies with the vertical split yard template.
All seam allowances are 5/8 inch unless otherwise stated.
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 stitching along the seam, 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 or a 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 Onesie Back over the Onesie Front, matching the shoulder notches.
With right sides together, pin the sleeve to the arm openings, 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 Onesie 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.
