Shower Curtain Help!?

[bleakoptimism.livejournal.com]

I hate to have to trouble you all, but I have been sitting pondering an idea. I want to make my own batty shower curtain, really, I don't want to pay $50 for one with a cool print. A bat design is pretty easy, but I have no idea how to go about getting it on there. I thought about permanent marker, but it isn't quite as permanent as it seems, I thought of some sort of glossy/plasticy paint, but it doesn't sound right, and then I thought of sewing the shapes on, but needle holes in the plastic would defeat the purpose of having the shower curtain in the first place right? I found a tutorial that said to use acrylic paint, but I can only imagine it peeling off, anyone tried it before, have any hints?

I looked back and in the memories as I remember someone posting a similar question about a shower curtain they wanted to paint the joker onto it, but I can't find it, it is probably under my nose.
