Any advice on tips/effects to create a photorealistic mylar balloon im

[kjjohanson]

I need to create several photorealistic images of graphics that appear to be on mylar balloons of various shapes. Any tips on how I might quickly replicate the effect of the folds? Or even filters/plug-ins that might help?

Links go to a couple sample shapes, with the folds/creases I would need to duplicate in other shapes:

I think you can get the effect you want with a displacement map. Here's a tutorial:
