Once in a while I try to work with no lines, building a piece from bigger forms to littler ones. It’s great practice for me since line dominates much of my work. So far, I’ve found it’s easiest for me to work like this with landscapes or still life, and much harder to with urban sketching especially with people in the sketch.
So here again is a favorite subject to sketch without lines: a view of Mount Umunhum from my neighborhood.
I did most of this line-free, but then you can see in this detail that I went back in with a graphite pencil and with white and blue colored pencil for some last details.
