Onesie, Twosie, Threesie

I’m sure you’ve already heard the news that I’m having a baby boy. Eeeek! If you hadn”t heard that, read the blog post on how I told my parents the sex of the baby. And my amazing brother, Erik from ELF Soap Molds, designed these awesome Baby Onesie Molds. In love! I had so much fun making these soaps in the soap lab. I’m hoping you enjoy the project just as much.
Download the FREE designs, BOY or GIRL, and print them on water soluble paper. If you’ve never used water soluble paper before, check out the easy video tutorial on Soap Queen TV. And one change since the video was filmed; our Water Soluble Paper is now laser-printer-safe.

Note: The hardest part of this project is deciding what you want your little onesies to look like. As you can see, I had fun making various designs.
ONE: First fill in the seams with pink or blue colored soap (maybe even glitter) using a dropper. It should take about two to three minutes to cool.
TWO: Melt a couple of ounces of clear soap base and let it cool down to 125-130 degrees F. Then spritz the seams with rubbing alcohol and pour a thin layer of clear soap. And here’s a new technique that I tried and loved: Cut out your design on water soluble paper, spritz it with rubbing alcohol and drop it in the clear soap. The method on the Soap Queen Video works great too. I just love experimenting with new techniques!
THREE: The other thing to keep in mind is your background color and how the design will look. I put a little glob of white soap base on the Soap Queen TV logo so the logo would show up white with my hot pink pink background.
FOUR: Then pick your background color and glitter. Shown in the picture above is Liquid Pink and Glitter in in Clear soap scented with Mangosteen Fragrance Oil. Mangosteen is a luscious blend of mangosteen, guava and green melon. Sweet and citrusy!
BONUS ONESIE: Just fill in the seams and add little drops of white or colored soap in the middle of the mold. Once it cools, spritz with rubbing alcohol and pour your final layer. For the seams, I used Liquid Pink in White Soap and for the background color I used Liquid Pink in Clear Soap, with Glitter and Mangosteen Fragrance.

    Where can I buy these!?!?!?! I’m new to the whole soap making thing, starting with the bath bombs, which seems a whole lot easier than this project! I’m hositng a Pamper Mommy baby showerfor my friend and we’ll use the Bath Bomb kit and the Goat’s Mik Bath tea kit at the party, I’d love to be able to include these onesie soaps as a favor but don’t want to screw it up!

    Hi, I was wondering what is the estimated time-line for this project. I plan on making these for baby shower favors but only have two molds. I need to make 24 or so…


    • says

      Since you have 2 molds (the more the better). You’ll have to do them in 3 separate rounds to get 24. It will probably only take you about 30 minutes to make 8 soaps, the longest part will be the cooling process. You could totally bust them out in one day if you did a round in the morning, another round at lunch then finish them off in the evening.

      It’s worth it though. I made them for a baby shower and they were such a hit!

    Yes! A little boy! We can’t wait to meet him. We have no idea on the names yet but we’re hoping to figure something out by April =)

  4. Lisa @ Serah's says

    Anne-Marie, I’m probably so late but congratulations!!! I just found out from looking at the pictures in your Flickr account that you’re having a baby!!! A soap prince. :)

  5. Anne-Marie says

    Switch to a laser printer and you won’t have any bleeding; it’s either that
    or get the special pigment based inks for printers that artists use and are
    available at stores?

  6. Anne-Marie says

    I can’t wait. He’s kicking up a storm and I already can hardly wait to meet him. He already seems to be staying up all day and sleeping at night. I’m hoping that trend stays =)

    Too cute!! Can’t wait to try my hand at these…now I just have to get Grandma to watch MY two little boys! You are going to have soooo much fun with your new little man! Congrats!

  8. Melissa Jensen says

    I am using the drop the paper in technique you show here and I am still getting bleeding. I am letting the paper dry for several days and also spraying with hair spray. Any ideas? Oh, and these are super cute by the way!!

  9. Donna Maria Coles Johnson says

    These are easily the cutest things I’ve seen all year. Makes we wanna have a little wee one again!

    [crickets chirping]

    Well, that passed!

  10. Amanda says

    Lol, that’s what I thought also… I was like…hmmmmm. What’s going on there? Then realized it was a back shot.

  11. Anne-Marie says

    Like double backwards? Or just single backwards? That’s intentional so that the logo looks right on from the front, since you’re putting it in/down on the backside. :) I’ll go check them to make sure we made them the right way though. Now you have me worried. :))

    Happy Soaping!


  12. Tara says

    Nevermind, I realize now that it’s a picture from the back of the mold! haha…should look a little closer next time.

  13. Evermore Organics says

    Oh wow these are great! The whale one is just killing me. Good job Erik! And I love your coloring. Ahhh loving these!!

  14. Melissa says

    Thank you for sharing these adorable soaps!! I love them! My baby girl #3 is now three months old… makes me want to have another baby just so I can hand out “soap onesie favors”!! Congratulations on your upcoming arrival! Very exciting!

  15. Anne-Marie says

    Thank you! We have soooooo much fun dreaming them up. We’re working on a really fun exfoliating lip scrub today.

  16. Anne-Marie says

    Spray alcohol INTO the seams first. It helps the soap spread more evenly. I should probably add that to the blog post … (airhead me today!)

  17. TeresaR says

    Looove these cute onesies soaps! I really need to work on my “seam” technique. I bought PJ’s syringe tool from you, but it’s still daunting to try them…this is what’s been keeping me from trying the gingerbread man soap. :}
