In my last post we talked about the savings, but in this post we’ll show you how to make these reusable bed-wetting underwear. Never buy Pull-ups again!

These bed-wetting underwear are made of 3 important pieces.

  1. A PUL (Polyurethane laminate) outer cover that is water proof.
  2. A soaker pad which absorbs urine.
  3. An inner layer that is also absorbent and comfortable against the skin.

Here is the PUL fabric I purchased on clearance from JoAnn Fabric. It is made by Babyville PUL. I also used the same fabric for the Wet-Dry Bag.



Step 1 – Pattern


I downloaded this pattern because it seemed the easiest for what I wanted to do and had variable sizes. There are many other patterns out there. You can add snaps or velcro if desired. I decided to sew the sides together so that they are real panties since I am using these for older children who wet the bed and not for everyday potty-training.

I printed the pattern out twice onto card stock. I placed one of the printouts face down and the other face up so that they formed matching sides. That was just faster for me than trying to flip it over and line it up for the other side. Tape them all together and it works for several pairs of bed-wetting underwear.

Step 2 – Fabrics & Elastic

  1. PUL – I purchased my PUL on clearance at JoAnn Fabrics, but there are many Babyville PUL products available online as well, like at Amazon. A yard will be make a couple of pairs, maybe even 3.
  2. Soaker Pad – I used sheets and t-shirt materials in my original pairs that I made. I found that was perfect for one child, but the other was a super wetter and needed something more. I made future panties with microfiber soaker pads. If you use old t-shirts, that is cool too. You will just need 8-10 of the soaker pad layers.
  3. Interior Fabric – Again to be cheap I used recycled sheets and t-shirts for the inner fabric. Soft against the bum and comfortable enough to sleep in.
  4. Elastic – I used a thin 1/4 inch elastic. As I explained in this post, I got it pretty cheap with coupons and such.

Step 3 – Cutting the Pieces


  1. PUL – Cut 1 of the shell pattern in the size that you want.
  2. Soaker Pad – Cut 8-10 of the soaker pad pattern to fit the size of your outer shell.
  3. Inner Layer – Cut 1 of the shell pattern in the same size as your PUL outer shell.

Step 4 – Sew the Soaker to the Inner Layer


Place all of the soaker pad layers onto the inner layer. See the picture above for placement.


Sew the soaker pad layers into place with a close together zig-zag stitch. This keeps the soaker pad in place. I did look at some of the designs that had snap in soaker pads, but I felt they added too much to the cost and might be uncomfortable for the child.

Step 5 – Sew the Inner Layer to the Outer PUL Shell


With right sides together, sew the inner layer and out shell together across the top and legs, leaving the sides that attach over the hip bones open for turning.

Step 6 – Attach Elastic


I found the most comfortable fit to be free standing elastic in the legs and top. I just attached with a zig-zag stitch the ends of the elastic to the underwear before turning. I cut the elastic 1-2 inches shorter than the length of where I am attaching it.

Step 7 – Turn it Right Side Out

It is a little tough to do with such tiny openings, but with a pencil using the eraser end I found it can be done without too much hassle. When it is turned it looks like the picture bellow. Kind of like a big diaper. Like I mentioned in the previous post, I made mine XL and XXL.



Step 8 – Sew the Sides Together


I decided to sew them together rather than use snaps or velcro to save cost. I folded the ends in on themselves and just stitched it straight up the sides.

Finished Product!


We used these for over a year. Occasionally we had some leakage. I did make more with a thicker soaker pad using microfiber auto-shop towels. They soaked up a lot more than the ones I made with t-shirts.
