After I posted the last previous Hotel picture, a present of an old book was given to me. CREATIVE DRAWING Point and Line by Rottger and Klante which was published in 1963. These are a couple of exercises that were suggested by the authors. There is so much more and I plan to continue this study.
It's funny, I always shied away from this type of work. I found, however, that it can be very meditative.
