Pastel drawings are artworks created using pastel sticks, which are made of pure powdered pigment and a binder. These sticks come in various types, including soft, hard, and oil pastels, each offering different textures and effects. Pastels can produce vibrant colors and smooth blends, making them popular among artists for both detailed and expressive works. The technique involves applying the pastel directly onto paper or other surfaces, allowing for layering and mixing of colors. Artists often use tools like fingers or blending stumps to achieve desired effects. Notable artists who have used pastels include Edgar Degas and Mary Cassatt, who showcased the medium's versatility in their works.
