I know of 2 web pages on the subject:
Hugo Elias's page(look under "Mass & Spring models"):
http://freespace.virgin.net/hugo.elias/models/m_main.htm

Xavier Provot's page, with some techniques which can fix some of the 
problems with the method demonstrated on the page by Hugo Elias:
http://www-syntim.inria.fr/syntim/recherche/provot/index-eng.html

I am planning to do a POV patch which can do something like this, but 
generalized to work with strings and gels as well as fabric.

As far as the problems with your attempt...could you be more specific? 
Do you mean "unstable" as in it crashes, or does the simulation just 
become chaotic and go out of control?
Did you add a drag amount?
