I havn;t messed with cloth since its first appearence in Maya ..
but I had one hell of a time attempting to get heavy corse cloth like a monks rob , or home-spun material..
You could try using a softbody similar to the girls dress in BINGO way back when.
I was getting somewhere with it as opposed to cloth was like silk no matter how much friction i added.
Never did finish the project since it was "for-fun" thing anyway ..but
just a suggestion to look into if cloth isn't making it.
Please post if you come up with a solution that works without your simulation time being rediculous.
