Many artists choose to draw first with a lead pencil, then overdraw this with the marker, then use a eraser
to rub out any visible pencil marks. If this method suits you...use it. I`d suggest trying a 2b pencil, and drawing in lightly, so you don`t have to rub too hard when it comes to rubbing out, and perhaps damaging the texture of your paper. The important thing is to keep up your practice whatever method suits you.
