I -really- should be able to figure this out on my own *hangs head in shame*

After seeing this post: http://community.livejournal.com/corsetmakers/1515739.html?style=mine#cutid1
I was wondering if anyone has seen any tutorials to make a ruched skirt exactly like the one shown
in the above link?
From what I can tell it is rows of gathered fabric but is the gather line sewn straight or  zigzig and is it sewn
horizontally or vertically?
I'm wondering how to finish off the rows of gathers as well. It appears that part of the skirt that are ruched
up are tacked in to place.

Thanks!
