When a dear niece was a three year old, she loved playing waitress and would write down our orders in child scribble with a distinctive pattern. Beginning in the upper left hand corner of the page she worked in bumps she felt looked like writing working to the right edge. Then she would come back to the left with the same words. She would make about three or four lines of that, then go around the outer edges of the paper. I was quite intrigued by the operation and the resulting drawing.
I began copying them. They were just right for working on hot summer days in my south facing studio. At that time (she is now a grandmother....), I worked with watercolor and produced a large series. I still have one of them hanging in my studio. I have long wondered if the idea could travel to oil paint.
