You
need to try and make your eyes slide along the lines at the same
time as the pencil, changing direction at the same time.
Don't
look over what you have drawn until you have finished. The exercise
should take about five minutes.
The
result, of course, does not look anything like a hand.
You
should repeat this exercise as many times as you can. You can use
this exercise with many other objects: a scrunched up piece of paper,
a leaf, a lock of hair.
