get a different model: an earthenwear jar. Using a small piece of
charcoal, draw a line to start off the sketch.
the charcoal flat and drag it under the line that you have drawn - this
will create the shadow. Limit yourself to draw a line on the left and a
shadow on the right to create the mouth of the earthenwear jug.
remember the process that we carried out with the bottle. Take the
charcoal horizontally and add the shape of the earthenwear jug. Always
vary the curve of the line depending on the object.
