I took part in Jake Parker's instagram Inktober event making a drawing everyday of October; these drawings eventually turned into one larger drawing by the end of the month.
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 also like using just black ink. Lately, I've been using this Platinum Preppy extra fine for my doodling. I like how different kinds of pens and tools can sometimes give different art.
