Pen drawings are artworks created using a pen, which can include various types such as ballpoint, fountain, or ink pens. This technique allows artists to produce detailed and precise lines, making it ideal for illustrations, sketches, and technical drawings. The permanence of ink also adds a unique quality to the artwork, as it cannot be easily erased. Artists often use pen drawings to explore different styles, from realistic portraits to abstract designs. The versatility of pen allows for a range of techniques, including cross-hatching and stippling, which can create depth and texture. Famous artists like Vincent van Gogh and Albrecht Dürer have utilized pen drawing in their works.
