So I turned into a plotter for my recent story and what i did was write out the general scenes and plots from beginning to end for the whole story on a notebook (like an actual notebook and pen) and for the empty gaps I didn’t know what to add I just put things like add dialogue/add extra scene it’s nothing too specific but it’s a decent enough outline of my story that really helps me stay on track on what I should be writing and be more organized.
I also had pages of my characters as well from physical appearance to what their personality is like so I don’t mix up too much.
When it comes to writing my chapters out I actually write out of order. When I use to write in order from the beginning of the chapter to the end I really didn’t like it and I got unmotivated to write faster. So every time I would start writing a new chapter I would usually start from the middle of whatever scene I’m writing or the end and then when I’m finished with that I write out the rest until the whole chapter is completed. Then I would go back and skim around, deleting and adding a few words/ paragraphs here and there to make the scenes go by smoother.
I know this is a really long reply but I hope this somewhat helps you a little… but if it doesn’t I guess an advice I’d give is to just experiment. See what you enjoy more, plotting or non plotting, see if you write your chapters better by starting to write from beginning to end or from end to beginning. Maybe you do better with summarizing every chapter before you write who knows
