Linda demonstrated a careful and precise approach to drawing, beginning with lightest tone - perhaps using a 4H or 2H, and on;y slowly progressing through towards the high B's, the darkest tones. Erasing can be smudgy so it is better to be sure of those blacks by working towards them slowly.

But one of the most valuable techniques was the indenting tool, a blunt point with which to score the paper before using the pencil, thereby creating a good effect of hair, fine feathering, etc.  Marks might be short or long as appropriate to the subject matter but light hairs appear almost by magic as one begins to add the graphite pencil shading.
