Using the brush to make the firsts strokes of the model

1. And is that you gonna trace a straight line in the canvas, and that will be the centre of the draw, and you gonna use the brush, or pencil, to see passing a centre line in the model what will be at the left and what will be at the right of the line.

2. you gonna stretch your arm because you gonna have to put the brush always at the same distance of your eyes, if the distances change you gonna miss. So you use the thumb to measure in the brush the size of the head and body and arms, how the model is far the pencil will be big for the model and you gonna measure in the paper marking with the pencil the measures that you find with your thumb, in the paper you gonna put the brush with the thumb still in the right place lean against the canvas.
