Drawing API "string" attatching 2 MovieClips?

I am a total Drawing API newb and I am trying to figure out if there is a way to do what would look like a piece of string (not straight) and make it attach to 2 different movieclips. All i can seem to figure out is how to draw a straight line and I can’t get it to attach to anything.
Any help would be appreciated.
Thanks!
