My husband has a chronic illness and frequently spends weeks in the hospital. I have been doodling each day while sitting with him and many of them reflect my thoughts at the time. Often appearing are desperation, hope, frustration, sarcasm, fear.
I feel like my drawings got a lot more dimensional and interesting once I was able to achieve variable line width. I love loading different colors into the pen and going HAM on paper that totally can't handle it. My sketchbooks crackle when I turn the pages. They buckle and heave and are exhausted from their tribulations.
