I abandoned color today in my abstract drawing, using only black and gray inks. I started with a black calligraphy pen, drawing bold swirling lines to form an abstract image. Then I used a fine line black pen to draw detailed patterns within those lines. I let my imagination take me where it wanted to go, in a loose free-form style.
I also used a fine point gray pen to fill in some areas with detail, and then filled in some of the small shapes with pure black. This was an exercise in whimsy and fun.
