Shape tool - choosing my nodes...

[rpc9943]

Hey there everyone...

I've been using the shape tool more and more at work and wonder... Is there a "preferred" or "best" way to choose nodes when creating shapes? Let's say we've got a french curl stencil that we want to make. Is it best to simply draw where the curves start and stop, or in the "center" of each curve as it bends? I am wondering if there's an art form to this tool, and if so, could you please teach me the technique?

thanks!

EDIT: Perhaps a silhouette of a mickey mouse type ears + body would be a good example...
