A lot of onesies are made of an extremely stretchy knit to fit a growing baby and so they require specific materials and techniques.
Onesies are made with a super stretchy knit fabric for good reason. I have learned the hard way that the usual techniques I use for t-shirts just don’t work for onesies. Here is one where I used regular iron on.
I’m stretching it to show exactly why this is a problem. You can see it is lifting up on the edges and no amount of ironing it back on would fix it. This is because the normal iron on has no stretch to it so it just peels off.

The way to remedy this is stretchy iron on. That’s where SportFlex comes in. This iron on vinyl is extremely flexible.
When ironing on, I suggest always overestimating your time. The EasyPress will make timing no thing at all because it counts for you. If you’re using a regular iron, the worst case scenario is you’ll burn your press cloth and you’d have to go way over time to that!
I created a checklist here that will help make sure you don’t make mistakes that I’ve made!
One problem you may encounter is when you’re pulling the plastic off. You have to go slowly because both the vinyl and the fabric are going to stretch.
If you want a onesie that stands the inevitable growth and amount of washes it is going to get, buy the right materials and take your time!
