What paint brushes do you use for oil painting?

For oil painting, it's best to use brushes made from natural bristles, such as hog hair or sable, as they can hold more paint and provide better texture and control. Flat brushes are ideal for covering large areas and creating sharp edges, while round brushes are great for detailing and fine lines. Synthetic brushes can also be used, especially for specific techniques or when working with water-mixable oils. Always choose a variety of sizes to achieve different effects in your artwork.
