Waterproof open wide zippered pouch

I'd been wanting to make this open wide zippered pouch for a while now, only thing I wanted it waterproof as well, to carry my 4yr old's wet swim trunks maybe or as a toiletry pouch. The tutorial is very well written and simple, so I had to make it. Finally 2 days ago I sat down and did it. Being a newbie sewer it took me a while, but I'm sure the next one will be faster.

I made the medium sized one without a contrasting bottom to keep it simple. Only thing I had to figure out was how to make it water proof. The lady at my local sewing store helped me pick out an iron on vinyl lining. So first

Cut out two 12" x 9" pieces each out of the exterior cloth, inner lining, stiff interfacing and vinyl lining.

Now take the inner lining pieces and the vinyl pieces. You would want the vinyl layer to be the inner most layer of the pouch, the part you see when you open the pouch.

Next peel off the backing on the vinyl and place it sticky side on the right side of the inner lining. Place the backing paper on it and iron it on medium, no steam. Make sure the iron doesn't directly touch the vinyl unless you want a melted mess.

This is how the white lining looked after attaching the vinyl. I similarly attached the stiff interfacing to the exterior pieces by steam ironing them together.

Next I treated the now vinyled lining as the inner lining and followed the steps in Noodlehead's awesome tutorial.

As you can see, I still have problems making straight stitches on small areas like the zipper tab.

And tada! All done! Thank you noodlehead! Going to make a ton of these now.

A pencil inside to give you a sense of size. Fits my sons swim trunks and soap bottle.

The shiny crackly interior, not as loud as I expected it to be, thanks to the stiff interfacing.
