the roughs for the pages are done digitally on my iPad with sketchbook pro. I have that printed 11x17 and I draw finals using a light box and inks. I almost always skip pencilling. I sometimes sketch a bit if something is not clearly defined on the rough stage in sketchbook pro, but not often. I prefer to go directly to pens as the line quality stays natural. I use a .3 and a bic Mark-it for most of it.
