I mostly write on my laptop. If I'm taking notes I may scribble thoughts on paper but the writing is done on keyboard to screen.
Sometimes though, when the words are given, when they flow fast and furious, capturing mood and moment then I write with pen on paper.
I write in a battered and old notebook. For ten years it has held some of my more creative work. The work that is not suitable for polite company. Work that is uncivilized, dark and a little dangerous.
It is never planned and always a surprise and tonight I've sat for hours at my kitchen table with mugs of warmed spiced cider and like a wild woman poured forth a poetic rant of a story.
