I'm working through the100 Drawings course with Jane Davies. It's a 10 week course where you create 10 drawings on cheap paper each week. The first week our lesson dealt with line. We worked with black, grey and white line and layers of white paint. I loved the simplicity of the prompt and pushing myself to cover up and let go.
Here are the first layers before adding layers of white opaque and transparent paint. I'm using graphite, black paint, markers, pencil and paint pens. More photos to follow.
