DIY Birthday Onesies Using Glitter Heat Transfer Vinyl

You all know how much I love my Silhouette Cameo….if you don’t know, then welcome to My Favorite Finds because you must be a new reader LOL!  I have made so many fun things with it.  You can check out my 9 Easy Silhouette Cameo Projects if you need some inspiration.  Or, check out my CC {Carrie’s Cameo} Pinterest Board.  So, at my sister in law’s request, I was MORE than happy to create some First Birthday Onesies for my sweet niece’s birthday party.

I started with some plain white onesies, heat transfer vinyl, and a number 1. I also downloaded a cupcake file for free to add to the onesie.  I came up with this:

DIY Birthday Onesies using glitter heat transfer vinyl and layering techniques.  Simple project for a new HTV user.

The thing is, once I made the first one, shown below, I couldn’t stop!  So, I thought that making a few birthday ones were in order.   I mean, little 1 year olds get messy with their cake…she had to have one post-cake, right?  This was a very simple project great if you’re using Heat Transfer Vinyl for the first time.  I found this handy dandy cutting guide from Silhouette HERE.

The most important thing to remember when you are using heat transfer vinyl is to “mirror” your image before cutting it.  That way, when you go to iron it on, it’s not backwards.  For a detailed tutorial on using HTV, see how I made my daughter’s Minnie Mouse Shirt.


I cut the number 1 out of silver glitter vinyl, and then the chevron pattern out of bright pink.  I ironed on the silver 1, and layered the pink over it. When layering, make sure you are covering all the area you’re ironing with parchment paper.


Are you ready to create something awesome with your Silhouette? Do you have questions?  If so, ask!  I’d love to help!



  1. This is so cute. I have been really trying to think of something I can make for my niece who is turning 4, I keep thinking along these lines, just doing it will a t-shirt of little knit dress. I’m just not sure yet…

  2. Did you iron on the one first and then iron on the chevron on top? Or did you lay both and iron together?
