Brush strokes refer to the marks made by a paintbrush on a surface, such as canvas or paper. These strokes can vary in size, shape, and texture, depending on the technique used by the artist. Different styles of painting, like Impressionism or Abstract, often emphasize unique brush strokes to convey emotion or movement. Artists can manipulate brush strokes to create depth and dimension in their work. Techniques such as dry brushing or wet-on-wet can produce distinct effects. Understanding brush strokes is essential for both creating and appreciating art, as they contribute significantly to the overall composition and feel of a piece.
