I really, really love good drawing, and recently I discovered professional artists' scratchboard - a medium in which black ink covers white clay, and scratching through the black ink makes a white line....the exact reverse of pen-and-ink. It's an unforgiving medium, as mistakes can't be corrected, but it rewards the patient draftsperson with dramatic images that emerge like magic from the dense black surface.

Scratchboard is a brilliant medium for rendering textures (eg, fur) in high-contrast light - and a wolf intent on the sound of prey makes a fabulous subject.
