For these Grahams Up the Tree drawings I used a Pilot Custom 823 with FA nib. This pen is legendary. It has a very soft nib and a giant vacuum filled tank of ink so you can write and draw for days.
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 have quite a bit of traveling planned this Summer...from NYC to Copenhagen to Venice to Berlin and a few more spots. Very much looking forward to all the different colors, cities, and cultures in the coming weeks.
