Tools Im using in this tutorial

Making a Baby Onesie doesn't require all the tools in the image. I recommend that you have a scissor or rotary cutter, some clips or pins, and a sewing machine. If you are attaching buttons or snaps you need that to. If you have all or some of the tools in the image it will make the job easier.

We do have all the tools available for sale in our store.


Sewing machines:

In this tutorial, we are using the Baby Lock Coverstich machine, a Brother 4234D Coverstich, and a Singer Tempo 70. The attachment we are using is a binding folder. You can find these binding folders for sale in our store. If you don't have a Coverstitch or an Overlocker you can use a regular sewing machine with seams made for stretchy fabrics.

We have two sewing patterns you can choose from. In this tutorial, we are using the Baby Onesie Sewing Pattern in this tutorial. But you can also use the slim-fit version. The Onesie sewing pattern is part of our most popular sewing pattern pack.
