Final answer:
Pencils are versatile for drawing fine lines and shades, but may not be the best for large color areas or permanent work, where pen and ink or paints are more suitable.
Step-by-step explanation:
Pencils are a desirable art medium because they come in varying degrees of hardness that allow for a range of expressions. Graphite pencils, made of carbon mixed with clay, provide a spectrum from soft (B) for dark lines to hard (H) for sharp, thin lines. Pencils are encased in wood, making them easy to handle and suitable for detailed work. Charcoal, another dry medium, offers a more velvety feel, especially in its softer forms, but can be challenging to control.
However, pencils might not be the best choice when large areas of color or tone are needed, or if a permanent, non-erasable line is desired. For these cases, wet media like pen and ink or painting mediums serve better. Pen and ink provide distinct, fluid lines and are often used for quick sketches or detailed finished compositions. Paints can cover large areas and adhere well to a variety of surfaces, but require preparations such as gesso to protect the surface.
