Drawings in graphite and charcoal

Each of my graphite and charcoal drawings is completely hand-drawn from blank to complete. I use Staedtler graphite pencils and General's charcoals on heavy paper, usually Strathmore. For some shading effects, I use ArtGraf water soluble graphite, either wetted or rubbed on dry with tortillon blenders. For fine white line work, I've used a scratchboard tool to score the paper, engraving white into the drawing. I do not use graphite overlay onto prints, tracing, or transfer papers.
