Distractions can be the source of dislocations and distortions in blind contour drawings. In the following example, I began the figure on the left just below the ear, but ended a distance away from the starting point. In the second figure, you might notice a rough curve inside it. I repositioned the pen (with the help of sight) and completed the body in more correct proportions.  Errors can be illuminating and even more interesting than true-to-life representations. I corrected one of them below to create an intelligible double portrait.
