As I was drawing Grandma Gladys, I was listening to an interview with Temple Grandin. At the moment she mentioned being a kid and reading a book about perspective drawing (she's a "visual thinker"), I looked up at my bulletin board and saw the photocopied pages from a drawing book -- a page that reads "Perspective Drawing."
I love that.
I love Grandma Gladys, too. She is exactly as I think of her.
