In another thread discussing how to arrange words for rhythm and clarity, someone mentioned writing skeleton sentences and adding details to it. A lesson from the book "Mastering the Craft of Writing" reminded me about this and I would like to know more about it. Do I simply write a complete first draft in all general sentences and then make them more specific, or do I embellish each sentence after I write it? What is the best approach to this? Also, if you are the person who mentioned this, what exactly did you mean?
