Great White North
I've heard that the Canadian illustrator Thoreau MacDonald, son of the Group of Seven painter J.E.H. MacDonald, used to draw landscapes only from memory, after he'd had a walk and come home. The cartoonist Seth talks about it here.
These scenes around Trevor's childhood home are always so striking when we first come up for a visit, I thought I would try to draw them from memory after coming in from a walk or a drive. I was happier with the results than when I drew a scene while looking directly at it (not posted here).
A materials note/aside: Craig Thompson is right - the Pentel pocket brush pen does work great on a toothier paper, in this case, a 9 x 12 Canson mix media sketchbook.
