As Oliver is starting to move into the 3-6 month size, I’ve noticed that brands can run very differently in size. A majority of his clothes are Carter’s brand and these seem to fit him the longest. He is currently wearing some of his 0-3 month Carter’s onesies while his Gymboree & Baby Gap 3-6 month onesies are getting too short.
I have a couple outfits in those brands that I really like so I was sad to see that the onesie was too short on him once the matching jackets and pants finally fit. I found some onesie extenders online but I did not want to pay $15 for three of them. I could have gone out and bought fabric and snaps and measured to make sure they lined up with the onesies I needed them for but that sounded more time consuming than it needed to be.
I found out that there are three different size and pattens for the snaps between the different brands. I went through his short sleeve onesies that he didn’t wear very often and found this Gerber brand one. This one came in a multipack and I love all of the other ones but this one didn’t go with anything else that he had so I was okay with cutting it apart.
I started by cutting the snaps off. I kept them together on the strip of fabric so I wouldn’t have to re-measure them later.
Next I cut straight across the bottom of the onesie through both the front and the back layers.
I straightened out the edges and kept the width slightly longer than the length of the fabric with the snaps.
Instead of using the sewing machine to attach the snaps, I stitched them on with embroidery thread by hand.
Using the embroidery thread, I sewed around the outer three sides to attach it. I made sure the finished side was on the inside and used the embroidery thread to hide the unfinished edges on the outside as well as protect it from fraying.
I did the same thing for the other side. Here is the finished product:
