Each writer has a different process to get words on a page.
Some type directly into a word processor, some write in long hand and some dictate into a machine. There are even a few who still use a typewriter.
I start in longhand, then type and print, then read aloud and make notes and adjustments, then print again. RINSE and REPEAT.
From the soon to be launched A Vow Unbroken, here is an example of a 3rd rewrite and the longhand edits and hopefully (but no promises) the final draft.
