This one was done in about 16 minutes. I decided to quit because I was just going to mess it up if I tried to put more lines in it. Again, I worked by visualizing something on my table: in this case, the face of a Catrina on my oil cloth over the table! My goal with this drawing was to keep the lines as long as possible, all horizontal. It got tricky around certain contours. Also, the pen ran out of thinned paint before I ran out of real estate going all the way across the cloth. I decided to put a small number in the corner to track them.
