The onesie jumpsuit tutorial!

You will need:
Fabric for pants
3 inch wide elastic
A Onesie (Make sure that your child can get into the onesie by stepping into the neck hole!  You need a onesie with an overlap shoulder, not with a regular neckline.)

(For chevron printing tutorial go HERE.) 

The first step is drafting a pair of pants.  There is a great tutorial on how to do that HERE at MADE.  You cut out your pants pattern pieces exactly how you would if you were just making a regular pair of pants.  Then you sew them together as you would a regular pair of pants, but instead of folding over the waistband and inserting elastic, you’re going to sew wide elastic right to the waist.

Measure your child’s waist and cut a piece of 3 inch wide elastic to that measurement.  Zig zag or serge the ends so they won’t fray, then sew them right sides together.  Press the seam allowances out and topstitch them down.  When you’re done the outside will look like this:

Now you’re gonna sew the elastic to the top of the pants.
Mark the middle and sides of the elastic with pins, and pin the elastic to the top of the pants.  Make sure everything is spaced evenly.  When you pin it you want the elastic overlapping the pants by about 1/2 inch.  In other words, you sew it on just as you would for a skirt. 
Now you’re going to sew it on, using zig zag stitch.  Pull the elastic taut as you go.
Next you’re going to put the onesie on your child.  Slip the pants on and mark with a pencil where the waistband hits the onesie.  Take the onesie and pants off.  Cut the bottom of the onesie off 1/2 inch under where you marked.  Then simply pin the onesie to elastic waistband.  Make sure the waistband is on the outside.


Sew it on using a zig zag stitch.

  2. This is super duper cute, and I apologize if I sound dumb, but how does the child get it on if it’s pants and everything is sewn together?

I love feedback! What did you think of this article?
