Here’s a warm-up exercise to practice drawing all the different ways to make a line look and feel. On a piece of 80 lb paper, draw several shapes. Make them different sizes, overlap them, and have at least one go off the page. Next, with a fine tip Sharpie, fill in each of the shapes with a different type of line. Be sure to include “contrast”, such as thick and thin, dark and light, short and long. Contrast adds interest, and the resulting design has a beauty all its own.
