Readers don't care if we are pantsers or plotters. They just want a good read.

I have a beginning and end in mind when I start, and maybe a couple of set piece scenes, but the rest 'appears' when I start writing. No doubt I have a subconscious plotting device helping me in the background, but I get out of the way and let it do its stuff.

And I give no thought to theme. I had a interesting conversation with a reader who was impressed with a number of themes in my first novel and the way in which I'd woven them together. I had no idea what he was talking about and had not been aware of any of these themes. Since then I have quoted him when asked about themes in that book as it makes me sound very clever.
