Since I didn't have the most current copy of The Goddess of Vengeance Work Pink Galoshes on my computer this past week to work on, I've been focused on outlining. I'm using a combination method, outlining a few chapters ahead, but still letting things develop. So far, I like this method a lot, as someone who tends to write by the seat of her pants rather than according to a strict timeline -- it's good to know what comes next, even though I don't feel the urge to know the exact events of chapter eighteen yet.
My outline is flippin' long, though. Right now I think every page of my outline is about 10-15 pages of fiction; my outline is more of a synopsis (and a detailed synopsis, at that; not the kind of thing any agent would want to wade through!).
I've read and been intrigued by several different outlining styles, like the snowflake method and chapter outlines or chapter summaries. For right now, though, what I'm doing seems to be working for me, even though this long outline is less efficient than some other methods (I've even found myself starting to outline Bodie's Men, when flashes of inspiration come to me, which I think is going be my 2010 NaNo project). We'll see what outlining method I settle into when I've written ten novels - part of being a writer is experimentation, in my book. :p
The one thing I'm sold on? Outlining somehow, anyhow. I'm so much faster writing now, but I'm also enjoying my writing time more. It's harder for me to get road blocked when I know what happens next and how my character is getting to that next pivotal scene!
Do you "pre-write", assembling your outline before you touch fingers to keyboard, make it up as you go along, or outline-as-you-go like me? If you do outline, what's your preferred method, or are you still deciding?
