I've been down this road before, I found the best way (for me anyway) to create weird organic shapes in one piece and easy to do is first create a flat grid pattern then do a network on it after that turn on the control points and go for it, tug, pull, push and scale is all you need.

Thanks for all the comments. I will give the grid - network - points method a shot. That's sounding like it would fit that work style.
