Cross-Hatcheting

Since I haven't bought a canvas and extra paint yet, today I decided to try to learn how to cross hatchet. I remember hearing the term when I was younger but never knew how to do the technique of cross hatching. Mr. Ganes was working on a piece one day that was a self-portrait he drew using cross hatcheting (I think that is how you refer to it). In his work the cross hatcheting was neat lines and never seemed out of place. It seemed to be a sort of print with how straight the lines were, unless he used a ruler and I didn't know. So today I tried to experiment with cross hatcheting. I started drawing windows that were outside the dance studio and trying to get shadows is harder then it looks. With pen lines don't always turn out clear and with cross hatcheting the shades may look to similar. When I had tried getting a shadow it would merge with the object itself and every line that was put in would just have the shadow remain the same shade. Cross hatcheting is a skill I most definitely need some work on.
