fabric paint question

[banana-fishie.livejournal.com]

I apologize in advance for not posting pictures with this post. I came across a Clutch purse at a local thriftstore recently and was wondering what sort of fabric paint I could use. The fabric on the clutch looks like imitation silk and I am thinking about using some silver fabric paint and a leave stamp I found at my local craft store to add a one of a kind feel to the purse.  What fabric paint would be best to use?
