Oil brushes are specialized painting tools designed for use with oil paints. They typically have bristles made from natural or synthetic materials, allowing artists to create various textures and effects on canvas. The shape and size of the brush can vary, influencing the application technique and detail in the artwork. These brushes come in different styles, such as flat, round, and filbert, each serving a unique purpose. Artists often choose oil brushes based on their desired outcome, whether it's broad strokes or fine details. Proper care and cleaning are essential to maintain the quality and longevity of oil brushes.
