This DIY is not really decor or home related. But since summer is here, I thought a simple tutorial for a wet/dry bag would be in order.

But first you may be thinking ….

What the heck is a wet bag?

Haha. I don’t know why the term “wet bag” makes me laugh. (I know, real mature.) A wet bag is simply a waterproof zippered pouch or drawstring bag that you can use to hold wet clothes, typically swimsuits.

But a wet bag has so many other uses. I use mine to hold the impressive collection of sunscreens I seem to have amassed. I just throw it right in my beach bag with my towels and stuff. I never have to worry about spills and goopy messes.

Why do I have so many sunscreens?? I don’t know. Apparently, every time I’m at the store, I grab a new sunscreen. (shrugging shoulders.)

I use my wet bag to hold sunscreens. Lots of them!

You can also use these wet bags to hold cloth diapers, wet clothes, snacks, drink cups, etc. You never know when one of those is going to give out on you! 🙂

Or, use them the opposite way – to keep your things dry and clean. Like your cell phone and other electronics.

These bags are a mom’s best friend!

FYI : I’ve also seen these bags called wet/dry bags, dry bags, bikini bags, and swim bags. You can buy these from the store too. But today, I’m showing you how to make one.

Let’s Make It Happen.

What Type of Fabric should you Use for a Wet Bag?

A waterproof one! Sorry, dumb joke.

Ok. You have several fabric options for making a waterproof bag.

  • There’s oilcloth, which I used for this tutorial. It’s slick on one side with a soft cotton backing on the other. You can just wipe it clean!
  • You could also use a clear Vinyl which you can pick up from most fabric stores and craft stores. A Beautiful Mess has a good tutorial for a vinyl one.
  • Laminated cotton is another option. It’s just cotton fabric with a laminated, waterproof coating on it.
  • PUL – or Polyurethane Laminate. It’s basically like laminated cotton but it’s plastic. I think. I’ve never worked with this material myself.

So – I really love oilcloth fabric. It’s easy to just wipe clean, it keeps things dry and contains messes. Here are a few things to note about this fabric. You can’t machine wash it and you can’t iron it. It will melt!

But a simple wipe down with a soapy sponge will do the trick for this fabric. To me, oilcloth just screams SUMMER. The fabrics are so pretty and colorful. They are almost retro looking to me.

And you can get some oilcloth fabric easily on Amazon! I know, I know. But Amazon makes it so easy to shop and that two-day prime shipping (now one day, even?) makes it so much easier to start your projects. Almost too easy.

You can also pick up oilcloth from your local fabric shops and online stores like Fabric.com.

I happened to have some extra fabric lying around from my last oilcloth project – these really cute outdoor coasters. Perfect for Summer! I used pinking shears to create the jagged edges. But you don’t have to.

Here’s another tip: Did you buy oilcloth fabric and it’s wrinkled or folded with creases? Don’t worry. You can’t iron it, but if you lay it out in the sun with heavy books on top, it will easily take care of those wrinkles and creases for you. I find that the wrinkles naturally flatten out over time too.

So guys! Let’s get to the tutorial. Woot!

Materials Needed to Make a Simple Swim Wet Bag

How to Make a Swim Wet Bag

Follow these easy steps and you’ll be on your way.

Tip: You don’t really want to use pins with oilcloth. It’s best to keep the holes to a minimum because it can cause the fabric to tear easier. So – I used binder clips. You can also use wonder clips. You also want a longer stitch because this will also create fewer holes.

Step 1: Cut out two equal, square pieces of Fabric

Oilcloth is slick on one side and cotton on the other. I wanted both the inside and outside of my swim bag to be that slick material, so I have to sew two pieces together. So cut two equal sized squares out of your fabric. Keep in mind that you will be folding it, so your finished product will be roughly half the size of your cut square.

Step 2: Line up your Fabric and Sew the Two Squares together.

oilcloth fabric is a great choice for swim bags
Line up your two squares and sew them together so each side has the waterproof lining.

Now you will just sew a seam all the way around, attaching the two pieces of oilcloth together. The cotton sides should be facing in. When you’re done, you should have a single square with the slick oilcloth (pattern part) on each side.

See the tips above for holding these fabrics together while sewing. You really don’t want to use pins and poke holes in the oilcloth. I used binder clips!

Step 3: Sew on your Zipper

Place zipper along the crease line and sew in place

Now, take your single square and fold it in half. This will create a little crease. Lay your zipper right side down on top of this crease and sew it in place. Yes – you are sewing the zipper backwards technically, but you will cut through the top to expose the zipper.

Because guess what?

Oilcloth doesn’t fray!! So you can clean up the edges later.

Step 4: Reveal your Zipper

Cut through the top of your fabric where you sewed your zipper. You should just be able to feel where the middle zipper part is. Cut all the way through both pices of oil cloth (remember, we have a double layer here.)

Your zipper should now be exposed! You can trim the excess fabric from the sides, so your zipper doesn’t get stuck on the oilcloth. You want it to look as neat as possible.

Step 5: Sew your Bag

Sew a zippered swim bag for summer.
Sew your bag inside out, then flip it right side out once completed for a nice, finished look.

Now that we have our zipper in place, we are going to sew a seam around the other three sides, completing our bag. You are going to do this so that you will flip your bag right side out when you’re done. The bag will look much neater this way.

First, ensure your zipper is open a bit (so you don’t sew your bag shut!) Fold the bag in half, lining up the edges. The zipper will be backwards and look upside down.

Sew a seam all the way around. Don’t worry about it looking too perfect. You can also trim excess oilcloth from the edges. Be careful not to cut through your seams.

Step 6: Flip your Swim Bag Right Side Out

Woot! You’re done!

You now have this cute little swim bag.

Or a wet/dry bag.

Or a dry bag.

Or a bikini bag. Whatever you want to call it.

Another Option for Swim Bags …

So I happened upon this website, which sells these wet bags. I love how cute they are! I found this site after I had already made my wet bag.

But it got me thinking …

You could totally sew a cotton fabric to the oilcloth fabric (so the lining is the waterproof slick part.) The only downside is you couldn’t really wash the front cotton side since it would be attached to oilcloth.

You could also place your zipper on the front side, as they have designed their wet bags. Super cute idea! I don’t really want to spend $30 some dollars on this but it’s nice to have the inspiration.

Don’t you just love creating your own knockoffs?

Old Navy also sells these cute bikini bags. This is definitely a good bargain.

I’ve said it before and I’ll say it again – if you can buy it cheaper than you could make it on your own, it’s probably worth it. UNLESS – you really enjoy the creative process. For me, I really enjoy sewing and making my own things and I already had the fabric. 🙂

So whether you need this swim wet bag for diapers, snacks, drinks, swimsuits, or sunscreens, you will be good to go!

Keep one in your car for emergencies. Throw a few in your beach bag or pool bag. Or give them away as little gifts! I would always take a few of these in pretty summery patterns.
