I love well-executed crosshatching but am not very good at it. Here is some practice from yesterday. I used a 4B pencil ... I am thinking a slightly harder pencil might give finer results. Experimentation doesn't always lead to good results. It is tempting to stay in one's comfort zone and do things the way one has always done them. But growth as artist requires experimenting, enjoying the process, and not getting too wrapped up in each and every result.
