DIY Birthday Onesie

When my daughter turned one I did what all good blogger mamas do: I made it her DIY first birthday onesie and outfit myself!

I’m so excited today to be sharing the first of three amazing posts! When my daughter turned one, I knew exactly what I wanted her to wear to her party, but all of the pieces individually were SOOO expensive. So instead, I did what all good blogger mamas do… I made it myself! Today I’m starting off the fun by sharing my DIY first birthday onesie.

Baby in ONE onesie for first birthday


Cricut Explore Air 2
Gold Vinyl
White Onesie

I started by opening my Cricut Explore Air 2 design space, and choosing from their MANY fonts. I found one I liked, and sized it so that it would fit on my onesie – 6″ width was perfect for this 12 month onesie.

Next, I place the gold vinyl flat on the Cricut cutting mat, and cut the design out. Remember that when cutting on vinyl, you want to reverse the image.
(After you click “Go” there will be an option to reverse image.)

Once the design is cut, you want to peel away the excess vinyl – leaving only the letters and the protective layer on the mat.

Next, take the transparent layer and place it on top of your onesie. You may want to iron the onesie first to warm up the surface that the letters will be placed on.

Once you have the letters centered and in place, iron them onto the shirt as per the vinyl instructions.

Make sure you use the “no-steam” setting on your iron, and that you hold the iron down for long enough to release enough heat.

There you have it! A beautiful gold, and sparkly onesie for your little one to wear at her first birthday party!!
I couldn’t get a smile out of her because she was too interested in my camera, but isn’t she the cutest baby anyway?! lol.
