Pick
up a thick piece of charcoal and start practising with it. You will
be able to see that the texture is very different to that of a normal
graphite pencil.
Another
way to use the charcoal is to use it flat on the paper. We get the
charcoal and we drag it across the paper, obtaining a very thick line.
Now
we are going to draw curves, using a small piece of charcoal.
We
should practise a lot, to get to grips with using charcoal.
