I have been playing around with some of the
exercises in the book "Syllabus" by Lynda Barry. In this exercise, you are to divide a page into 16 boxes. Select 4 nouns from one of your daily diary pages and draw each in a separate box in a column (45 seconds each in non-photo blue pencil). Then draw each thing 3 more times from another viewpoint. Ink them. Now you have 16 new drawings!
I have been neglecting my drawing~doodling time this year ... but am making an effort to draw more (of anything).
Here are some other folks I have run across who have done the "Four By Four" exercise:
