Hatching

The Visitor by Mary Cassatt.  This drawing is a clear example of hatching.  I enlarged the image to show the clear lines that assist in giving the drawing volume.  The lines on the left wall give the image volume.  The closer the lines on the woman's clothing the more shadows are created thus giving the image depth and adds volume to the person. The upper right side of the woman's dress is not as dark which gives the impression of shadowing.
