Editing is a BIG job, and sometimes it can seem like it's taking forever. Trying to get a story to flow and hit all the emotional beats at the right points… Getting your head around the nuances of voice, show vs tell, and the dialogue flow… And we shouldn't forget the dreaded punctuation and grammar.
But sometimes, editing has nothing to do with voice, writing style, or what might be in the dictionary. Sometimes, it's the little details that define our characters or settings that need to be filtered through an entire manuscript (or multiple manuscripts).
When you are working with a long story, the little details can sometimes get lost among the screes of words in all the random notes and files that might be thrown all over the place. This is particularly problematic when working in a series where particular characters might be used in story after story.
To help keep the little details straight, create character style sheets as you go.
