If you are finished with the assignment from Thursday and Friday then please read the section in the art history book on VALUE.
Find the graphite sticks in the back and do some sketches of found still lives - ie objects you put on your desk - try your jackets, shoes, or scarves - and using only value - NO LINES - do a descriptive drawing of the still life. Emphasis on making it look rounded and three-dimensional. Don't worry if it look 'real' or in proportion - worry that it has a full range of value from white to black and that it turns in space.
Use small paper and fill the whole page with the motif - no background!!!
