I have resumed doing a series of koi drawings of different sizes. And in between drawing the koi, I do fast drawings after old masters. I pick up whatever book is lying nearby. (A book on Paul Cezanne is often one of those lying near by.) I flip to a random page. And I start drawing.
Looking at paintings I love — by old masters — with pen in hand — sets my thoughts free. I copy Cezanne fast. Pick any spot in his picture that catches my interest and just dive in.
It’s like having a conversation with someone from the past. And we speak entirely in images.
