• Use one corner of the vinyl eraser to erase the lines that don't belong.

• If the final lines are darker than the mug, use a kneaded eraser to lighten them.
  • Form the eraser into a rounded shape and tap and roll it over lines.

• Fill the mug with light hatching.

• Make the hatching look as smooth and even as you can.

Step Five

• Now look for obvious shadows and hatch them until they darken.

• To get the darkness right, compare each area to the other parts of the mug as you hatch.

• The shadow shapes are like a jigsaw puzzle with hard and soft edges, so draw them as you see them.
  • Hard shadow edges end abruptly.
  • Soft shadow edges end gradually and blend into the next area.

• There will be a lot of reflections inside the lip. Shade "around" the most obvious ones.
