DIY Baby Onesies

Hi, I name is Lisa and I have a baking blog called The Bearfoot Baker. I love hanging out in the kitchen creating new recipes and making cookies. When Kristyn asked me to make something for a baby, I was thrilled. I make a lot of cookies and I wanted to use some cookie cutters in a unique way. I came up these DIY Onesies.

Super cute DIY Onesies made with Cookie Cutters

The possibilities for designs are endless. Seriously, have you seen all the cookie cutters they make these days? I can’t wait to make a DIY onesie by using all kinds of bug cutters. Or maybe a cute onesie with butterflies for a little girl.

You could even use this idea for a baby shower. Have a box full of cookie cutter and a little paint and watch everyone’s creativity take over. I bet you will be amazed by their creations.

DIY Onesie Supplies:

Onesies (plain white or solid colors)
Paint Colors of Your Choice
Textile Medium (mix with paint according to the directions. It makes the paint on the fabric flexible.)
Paint Brush
Cookie Cutters (get them here or here)

I got these onesies at Wal-Mart and it was about $7 for three. They didn’t have any solid colors but I think pink, blue, yellow, red, and green would be precious for this project.

Begin by washing and drying the onesies.


When you open the package, keep the little cardboard form to slid inside onesie to keep the paint from bleeding through the back. You can use cardboard or card-stock if you are working with more than one at a time.

Next, determine what size cookie cutter you want to use. This is a 1 3/4″ by 1 1/4″ . Mini cutters work great for newborn onesie.


Put a small amount of paint mixed with the textile medium on a plastic lid ( this is a cool whip lid) and dip the cutter into the paint. Next, press the cookie cutter onto a clean paper towel to remove excess paint.

Then, press the cookie cutter onto the onesie.

Next paint the shape.

I used a little blue paint and the end of the paint brush to add the water drops and puddles. Once your DIY onesie is dry, use a fine detail brush to make outline and detail the fire hydrant. Or you can use a Fine Tip Sharpie. A Sharpie will bleed on the cotton and it will look bad. You could make a large puddle at the bottom of the hydrant and write “I Leak” on the paint.


You don’t have to paint in the middle if you don’t want to. The cookie cutters make a great outline.


The end of the brush makes great dots and drips.


The only other thing you need to know is you must heat set the paint. Let everything dry completely and then, iron them according to the fabric directions. It may fade a little over time but, I think that makes it even cuter.

Thanks Kristyn for allowing me to share these DIY Onesies with you all today. It has been a lot of fun!


How uber-cute are those onesies?!

Thanks for the tutorial, Lisa! Never in a million years would I have thought to use a cookie cutter for a pattern – GENIUS!!

    Hi I love your onesie ideas and it will definitaly be on my list to do for my next grandchild.. I receive your blog by email and reader (but reader is going away). I don’t understand about facebook limits. I use pinterest because that is more intuitive to me and to remind me where I saw “that wonderful idea” Call me old (I feel it when I realize I am old enough to be your mom) but face book and I are not on the best of terms, Why? I forget about it. It is complicated and I don’t feel particularly safe there. Unless something points me there in an email or my daughter s post something that gets forwarded to my inbox…..yes I forget., and I do follow you. Why do you have to pay to post? I really don’t understand. Can you explain? I love all the wonderful ideas you have and have tried and loved many. I share my albums on Google plus so I can limit views to people I kinow. I’m not entirely to blame as three of my children have degrees in computer science and they have made me a bit paranoid. ;)
