Okay, let's sketch only with my left hand for a day.
The results...
... aren't anywhere near as interesting as the doing of them. I seemed to have more arm that I was used to. I don't know what I do with my right elbow when I draw, but my left one suddenly had it's own ideas of it's place in the physical universe. It was like wrestling an ironing board. The line, as such, is not so different, but the feeling of drawing it was the most unusual thing.
Will do more. If only to conquer the elbow.
Bad elbow, down, down.
