DZO Olivier, a French artists whose intricate illustrations we have featured before, recently decided to put aside paper and canvas to experiement with drawing on less traditional surfaces. "I always varied pens but rarely drawing surfaces. Out of paper for a short time, I turned to the two inert materials: stone and bone. These inert materials seemed so ordinary! This is not the case. They are still "living" materials: rough, bold, smooth, cracked, absorbent... Taming the variety of surfaces on a volume is a real adventure! So I put aside the paper and canvas fabric to experiment with new drawing sensations. Hand fits. The fingers feel every bumps. The spirit leaves guided by reliefs. The tip of the pen folds and unfolds. I even had the feeling that this matter thank me for taking care of. Today, I look differently. I understand them differently. This experience has enriched my own drawing skills. The "inert and dead" matter, gave me some lessons. The following images are the result."
