Wilhelmina has now been diaper-free and using one-wet trainers since she was about 5 months old. One-wet trainers are great, they are underwear with a bit of absorbency so that a miss doesn’t mean a mess. They are however quite expensive between 15$-20$ each. Because I can sew, I can’t justify buying them.
I made quite a few pairs before finding the perfect design for us and I am really happy with the ones that I now make. They stay up well, have no bulk, and fit and look like underwear.
The underwear itself is made from a stretchy knit fabric (I have even used old onsies) The Soaker has a layer of flannel, a layer of Zorb or another absorbant material and a layer of PUL. You also need braided elastic for the waist and fold-over elastic for the leg openings.
You can download my pattern here. (I don’t mind sharing, but please don’t use this to sell unless you buy a license which is at the end of the post) These fit Wilhelmina at 5 months and were still fitting at 18 months when we stopped using them…
First cut the pieces out… giving yourself a 1/2″ seam allowance around all sides except on the fold. (btw… If you want to make these bigger just add more seam allowance.)
Next cut out the pieces of the soaker. One flannel, one PUL and one of your absorbant material and then a smaller rectangle of the same to add a bit more absorbency without adding bulk.
(here is the flannel, I forgot to take a pic of the other pieces…sorry )
Sew the absorbent material together and add a few lines of stitches going across the middle. This makes it less stiff and contours the body more instead of the soaker sticking out…
Put the soaker together by placing the flannel on top and the layer of PUL (shiny side in) on the bottom and sew the pieces together (serge or do a zig zag stich around the edges)
Now that the soaker is done, it is time for the underwear.
Sew the three pieces together. (the largest part of the crotch piece fits onto the back piece)
Next is time to put the elastic in the leg holes.
(This is Fold-over elastic if you are wondering)
Fold the elastic over one end of the leghole edge and stich it down, then using a zigzag stich pull the elastic slightly while sewing it down the leghole edge.
It should look like this when done.
The do the same on the other side.
Next place the finished soaker on the underwear piece with the round part on the front of the underwear. Using a zigzag stich, sew it in.
Now the soaker is in…
With the right sides of the underwear together sew and/or serge the side edges.
Measure your little ones waist and then subtract about 10% and cut the braided elastic to that length. (Wilhelmina’s waist is about 17 inches so I need about 15 inches)
With the underwear inside out, sew the elastic around the top edge. Again using a the zigzag stich, and stretching as you sew. (the ends of the elastic should meet or slightly overlap)
Finally, turn the underwear right side out, fold the elastic over and sew it down, stretching again as you sew.
Hope you enjoy them as much as we do!!
Not everyone can sew or has the time to do so, so if you want to make these One-wet trainers and sell them, you may purchase a license to do so.
-One Limited Commercial License = One pattern / tutorial
One License must be purchased for each person who makes or sells the tutorial / pattern (so if two people are making them for an etsy shop of craft fair, both must buy the license)
I still retain copyright on the tutorial / pattern itself.
Lastly, when selling or listing the item, design credit must be given to A hippie with a Minivan with a link to this site or pattern.
Also, if you wish you may send me the link to your shop so that I can send people to you!
By purchasing the license, you agree with the terms
Thank you! and happy sewing!
