When I first took drawing class (way back a zillion years ago) I had a thorough dislike for a method called 'blind contour drawing'. (Blind contour is drawing while looking at the subject and not looking at the paper). I remember the teacher would bellow "Blind Contour Everyone!"...and I would groan uugghhhh. I suffered through those sessions, longing to look at my paper. I seldom liked the results.
Well! Recently, however, I started drawing blind contour in my little sketchbook. Why, I don't know..I can't account for why I appreciate it now...but I do!
This is the reservoir in Mt. Tabor Park...right next to where I live.
(I'm glad I hopped out of the car to "blind contour" sketch the Reservoir gatehouse...and I know my old drawing teacher would approve).
