For myself, I write...and as I write, I'll cross out, edit, insert, 3the text. If I readit orcomeback to it later, that'll ahppen again...sometimes I might redo a paragraph, but usually only if I knew I was unhappy with it at the time of writing.
There have been occasions, however, when I've done a section anew (not having the original on me at the mo) and it usually ends up quite different, (eg: more detail & indpeth, as opposed to a semi-summary one time). But generally, I don't have drafts - I have writing, with each line of paper sprouting notes and changes, and sentences and parapgrahs living in the margins with convoluted arrows directing them to their new homes.
