I'm in the middle of my first past revision for the second book in the Sweet Venom trilogy, which is due in to my editor June 1st. Although my writing and revising process tends to change from book to book, there are a few essential supplies I must have in order to get through it.
1. Sticky Notes — I use these, in various colors (sometimes color-coded by type of comment, sometimes by character, like in Sweet Venom) to: mark my daily page goal, flag the first pages of chapters, and to add large sections (a sentence or more) to the manuscript. Right now, I'm using green ones for Grace's notes, orange ones for Gretchen's, and pink ones for Greer's.
2. Highlighters — These are mostly for fun. I'll either highlight the chapter title (color-coded to which girl's POV I'll be in for that chapter), use them to mark up my countdown calendar (green for writing days, orange for revising, pink for days off when I can get life stuff done), or just to pretty up pages of notes in my book notebook.
3. Pen and Pencil — These are for the real work. For marking directly on the manuscript page, I use a mechanical pencil (Pentel in .9mm lead, if you want to be specific) so that I can erase and rewrite (over and over again) as I'm trying to get the line just perfect. For longer additions on the sticky notes, I use a pen (Uniball Vision Elite in micro) so it doesn't smear when I smooth the sticky note into place.
4. Manuscript — I feel like an eco-fraud every time I get my manuscript printed out for my revision pass. But I have discovered that my brain just does not process revisions in the same way on the screen as I do on the printed page. And I do get the manuscript printed on recycled paper, to offset the waste. I contain the manuscript in a big white 3-ring binder with a cover page that has the working title of the book.
So that's what I need to get through my revision process. Do you have any special supplies that you absolutely must have can't live without while you're writing/revising/doing homework?
