I am not a trained copywriter, but I have had my moments when it comes to headlines, taglines and concepts. I am a pretty darn good proofreader and editor. I can take your rough wording and organize your thoughts, make sense of them, add headings, highlights and, as they say, kill your darlings. (Do they really say that? Yes. Yes they do.)
As with illustration, I prefer working with professional writers—ideally collaborating to get a great result. I know some, if you don’t. Regardless, let’s talk about what you need to say before we actually say it.
