what is the difference between the types of line that artists use when they make contour line drawing and sketches?

Answer

:First is the standard contour drawing. Contour Drawing: A contour is the line which defines a form or edge – an outline. ... Blind Contour: Blind contour is similar to a regular contour drawing except the artist keeps their eyes on the subject they are drawing and does not look down at the paper.
