Line Quality: Cross-Hatching
Cross-hatching is a common line quality that is similar to hatching, but slightly more complex. It involves drawing parallel lines in two different directions so they overlap each other. This is a way to create shading with graphite pencils, pens, colored pencils, pastels and even ink or watercolor washes.
Here are some pros and cons of the method of cross-hatching as a way of creating shading in a drawing. Try this method of mark making with a few different materials (pen, pencil, pastel) and see where it is best used for you.
