Here is another page showing behind the scenes work of how an artistic item comes into being. Most people see only a finished painting or sculpture, and never get to see the preliminary work done by the artist as they decide on composition, pose, size, etc. These sketches show that part of the process. The "Color Comps" page shows how the color scheme is determined. Sketches are usually thrown out when the picture is finished.
This page shows a charcoal sketch for a drawing, with tests of soft and hard vine charcoal, and compressed charcoal, with a note about the size determination. The line to the right shows I decided to narrow the composition. Compare the sketch with the drawing.
This is the start of a litho on a metal plate of al Muller, violin maker. The red lines are pencil that will not affect the litho. Black lines are done with a litho crayon, and are the beginning of the drawing. The litho is reversed from the drawing, and will reverse again when printed.
This is a 20 x 16" charcoal drawing done on brown wrapping paper. The subject is Coventry Patmore, as painted by John Singer Sargent. I liked the profile, and did it as a study. I would not use brown wrapping paper on original work.
