Mayhem took five Socrates' Chidren took three but I may rewrite it. Looks like Coffee Killer will be three or four Those are complete rewrites not edits.
I edit and rewrite as I go along. But sometimes I 'finish' a story and return to it a few day/weeks/months later, and rewrite it. Some stories have had more than 7-8 'finished' forms.
I generally don't do complete rewrites, but I do read through many, many times after I've finished and do a lot of editing. I've read through and edited as many as a dozen times before I'm satisfied that it's as good as I can make it.
As many as it takes. I'll usually edit a story two or three times before I start sending it out. Then, if I get a rejection, I usually take a look over before sending it out again (which may or may not result in a redraft), especially if the rejection has included any specific advice or highlighted any particular problems.
I normalliy re-edit my story after every ten pages. Because The Invisible Hands of Love, my first attempted movie script, is a movie script, I would try to redraft it as many times as possible because my goal is to keep the sentences lean and clean and try to keep the margins in line. I don't often do re-writes in my novel, because I normalliy turn them into a movie. This is where I do the re-writes from, is in the script by itself.
While I have several completed stoires, I have no intentions of getting any of them published. At least not yet. So I just go through them once or twice to fix bad sentences and grammar. If it was a story I really wanted to publish though... I'd probably go through it over and over until I knew every word by heart.
