How to Sew a Wet Bag

How to sew an easy wet bag.

How to make wet bags easily and quickly. These make great baby shower gifts and are a must have for parents!

I LOVE (affiliate link) wet bags. If you aren’t familiar, wet bags are a great way to store items that are wet or dirty. They have a lining of PUL which holds in the wetness… this is great when transporting items like dirty cloth diapers, wet bathing suits, etc.

It’s not 100% waterproof- if you’ve got a soaking wet bathing suit then it WILL leak through eventually- but if you wring it out first, then you’re golden. I use wet bags for everything- we keep one in the kitchen for dirty rags, in my purse for diapers, and in our bathrooms for diapers and wipes too.

I’ve made them a couple times, but I needed more for on the go. I also wanted a couple for gifts for friends.

I found this great tutorial on how to make a simple wet bag easily so I used it to put these together.

A couple of changes I made while sewing them:

  • I cut 4×16″ strips of fabric for straps and folded them in half… for some of the bags I added two straps, one strap, or no strap. I recommend using at least one. You add snaps to the ends of the straps so you can easily snap them around a towel rod or such. I actually like to bring one to the grocery store and stuff my wallet inside… then I can snap the strap around the front of the shopping cart for easy access to my stuff.
  • I sewed a straight stitch around the wet bag when I sewed the sides using a walking foot. The slippery side of PUL is kind of a pain to sew so serging ended up being worthless. The walking foot made it faster and easier with minimal pinning. I think you’ll also have less issues with leaking with a regular straight stitch- lots of holes doesn’t make for great waterproofing.
  • Again, I don’t like working with the shiny side of the PUL so I tweaked the instructions so I didn’t have to worry about it. Seeing I couldn’t use my walking foot for the zipper area and I needed to use my zipper foot, I got around the issue by making sure that the pretty side of the PUL was face up. Then I faced the zipper down on top of the PUL and sewed it on (left). Once that was done, I top stitched the zipper onto the PUL (right). 
For the black and white wet bag, I decided to change it up a bit. I used the same size cut as the others. I placed my PUL right side down. Then I took my zipper and placed it on the back (shiny) side of the PUL and glued it down. I sewed the zipper, then I used scissors to cut the area where the zipper is. It’s not the prettiest edge, but PUL doesn’t tend to fray so I figured it would work. I like the position of the opening in the front of the bag, but I like the LOOK of the bags with the zipper at the top. 


Here are some final pictures:

Are you considering switching to cloth products? Do you love cloth diapering? Curious about cloth products such as cloth menstrual pads, wet bags, and unpaper towels? I just released a fantastic book that is ALL about using, laundering, and sewing reusable cloth products. It even includes instructions on this project!

Thanks so much! I appreciate the kind words :)

Wet bags are amazing. I think I have 4 little ones in use, and 4 big ones. Oh wait... then 2 more fleece ones, and one in kitchen for linens. #imighthaveaproblem

I'm starting swimming today right after work this would be great to have now. Too bad I'm afraid I sew my fingers together on a sewing machine

I usually only sew my fingers together when hand sewing. ;) The machine makes it a bit more difficult to get your finger caught under the needle I think.

Famous last words of course....
