You said it's a fabric-like material. Water down some fabric paint and use it, it'll look all drippy. Little messy though.
olol I'm stupid.
I've been looking for fabric paint for awhile now. Walmart doesn't have any, and there's not a single place to get art supplies for miles - just another benefit of living in the middle of nowhere. My dad's girlfriend is an 'artsy' sort of person though, so I'll ask her about where I might be able to get some.
Just now I managed to finalize all the other preparations and I should be able to film a few scenes tomorrow. I'll have to get the ones with paint in on Sunday.
stuff's getting close though. :/
