Although I make my drawings in pen with watercolor, I allways make sketches upfront. I mainly use Derwent and occasionally I make sketches with ballpoint (when I'm in a hurry and afraid to lose the idea during the process of finding my pencils).
I'm used to draw in this style for quite a while now, with mostly the same subjects. Perhaps it's time to make a change in subjects, for instance: urban scenery, landscapes, portraits, animals, etc, etc.
But for now I drew my sketching tools: pencils, cutting knife and sandpaper and eraser. In pen with watercolor. Of course.
