The last topic in the Line Qualities chapter deals with hatching and cross hatching. This is where tonal variation can be used in line drawing by using parallel line (hatching) with parallel hatch lines to create different tonal variations. As usual, Smagula's explanations on the technique are pretty much non existent, so luckily I remembered some practise I did form Bert Dodson's "Keys to Drawing" book a few years ago, where he explained Giorgio Morandi's (a famous cross hatcher) technique in clear detail, showing demonstrations of the four values that Mornadi used in his artworks - a light, middle light, middle dark and dark. He didn't use solid blacks. You can see examples of the four values of cross hatch in my above drawing of a paper bag.
So the exercise this week was to draw a crumpled paper bag with black pen. Basically you had to analyse the light and dark areas of the creases and define them using cross hatch style. It was important not to cover the entire surface with hatching, as the blank areas represent highlights. I find this style of cross hatching line drawing to be relaxing and a fun way to explore tone.
Above are some more practise cross hatching technique exercises I did a few years ago. The tea pot on the right is a still life is based on the methodical style of Giorgio Morandi (1890 - 1964). You can see more examples in this of the four tones used in cross hatching.
