Carol Sloan again.
I forgot to post a link to the book that I saw this lesson in - my bad!
It is a book that I bought at a local library's used book sale for a dollar.
"The Natural Way to Paint: Rendering The Figure in Watercolor Simply and Beautifully"" by Charles Reid can be found on Amazon if you want to have a peek at it. I have only worked on this contour drawing section, which I enjoyed very much but need lots of practice at.
Thank you, anonymous commenter for asking where I saw it at!
