My son needed to borrow my iPad for a spell as his laptop needed some repair. As he is in school and needed it more than me, I offered him the use of it. While it was gone, it forced me to draw in my sketchbook more than I have in some time if I wanted to work in front of the TV at least. I thought it would be good for me. I did lots of studies but really focused on simple drawings in black and white ink. All done with a simple #2 pencil, a few sharpies and a white gel pen.
