Make your own wetbag! A tutorial (my first!)

I am doing this for a friend because explaining the process with words wasnt working out. I am a bit worried about letting a pattern I created (with ideas from other places) get out. So if you are in the same circles as me please dont sell this specific bag. BUT if you are on etsy, etc, then go for it. ;)

First I have my fabric. You can make it whatever size you want. I wanted mine to be a square so I did a giant rectangle. But keep in mind that the width (the top where the zipper goes) has to be SHORTER than the zipper is long. So if you have a 20 inch zipper then your fabric should be around 17 inches across. I think I have a 15 inch zipper and this fabric is 12.5 inches by 24 inches. I also cut a piece for the strap, it is about 2 inches by 9 inches. You can make this as long or short as you want. I make my bags with longer straps.
First you need to sew the strap. You CAN NOT iron PUL, so you basically have to make the fold with your hands. I try to pin this fabric as little as possible because I dont want to pierce the fabric more than necessary. So here I am holding the fabric with no raw edges showing.
Here is the strap on the machine. It is not necessary that no raw edges are showing as PUL doesnt fray. But it looks better if you have it doubled. Sew from one end to the other.
And then you have your strap.
Next you need to sew your zipper on the edge of the fabric. Always remember FACE TO FACE. So the face of the zipper is facing the face of the PUL. This is not an easy task. PUL is slippery, so dont expect to get it right the first time. YOu may need to try this more than once.
NOTICE I AM USING MY ZIPPER FOOT! Sewing the PUL onto the zipper. FACE TO FACE.
Sew all the way to the end.
Next you need to sew the other end to the zipper. . Ignore the cut fabric, I had to trim that off. And again, sew it face to face.

When you are done it will look like this. Its like a giant tube. You can stick your arm inside of it (I tried to get a picture but my camera wasnt cooperating).
Slide the zipper down to where you want it to be. I usually do it 2 or so inches from the top. Here it is. Next take the strap and side it where you want it. I do it above the zipper.
Pin it in place.
Now sew both sides. So that you are closing the "tube". Sew over the zipper (notice I went back to my walking foot). Be sure you dont sew over the tiny metal piece of the zipper, it will break your needle (trust me I know!).
Its a bit more difficult to sew over the strap but you can do it! Pull out the needle holding it in place right before you get to this spot. If your machine is having issues with the PUL (as in skipping stitches) then you probably need to change out the needles. I wish I could remember which needle is best (a higher number or lower) but I cant..so try out different ones. Maybe a middle size one.
So then you are almost done. Lay the bag down.
Trim off the ragged edges. Just cut the zipper off, make sure the zipper pull is not on the part you cut off! lol.
This is where a serger comes in handy. You would just serge the edges. But since I dont have a serger I do a zig-zag stitch with the foot half on and half on the fabric so that the thread wraps around.
Turn it inside out and you are done!! A beautiful wet-bag!
I had issues with this particular PUL de-laminating. I am hoping that that was just a bad batch and that this will be fine.
If you make one post a pic for me to see!
