The Natural Black Fitch Brush is wedge-shaped with the hair receding from the sides. This shape allows the artist to paint very thin edges and control the shape of the brush stroke. These Artist Fitch Brushes are a cost effective alternative to the Natural Scenic Lining Brushes. The bristles have a tendency to brush out. Great for beginner scenic artists, quick touch ups or projects where clean up is difficult. Can be used for oils or acrylics. They are ideally suited to portrait painting and detail work. The natural fill in this artist's brush holds more paint than a synthetic brush, allowing paint to be applied more evenly and with longer brush strokes.
