I used it recently for a diaper changing pad plus a pouch that could hold wet clothes. I bought mine at Joann's. A little tricky to sew on the plastic side; I had to put the walking foot on. Teflon foot would probably work too but I don't have one.
It's really not a bad texture. Much more skin friendly than laminated cottons (won't stick to you). One side is more plasticky, the other side is a soft knit, but even the plasticky side isn't too bad.
After I washed my pouch I filled it with water to test how waterproof it was...it held water like a jug. I was surprised, I expected some seepage but it held water as long as I was willing to stand there holding it (it was probably about a half-gallon of water in there...my arm got tired!). So the Joann's kind must be the kind that seals up in the washer/dryer.
