Didn't realise you had write your first draft, and using a fountain pen!! The only time I get to see handwriting nowadays is at Christmas time, and those are getting rarer.
I always have a pile of scrap paper by my laptop where I can scribble down notes, it helps me to visualise things better, at least at the moment I write it down, and it also makes me feel better better because I've physically done something that we do less and less nowadays.
