The small 3 Fan Brush is used to paint the same spectacular effects that the larger 6 Fan Brush creates, but with more detail. Devote some practice time to this brush and you will be amazed at the effects you can achieve. The Bob Ross Landscape Brushes are special brushes made from a mixture of natural and synthetic bristles and shaped to Bob's very precise specifications for the Bob Ross Wet-on-Wet technique. Remember, ordinary brushes are not the same and cannot produce the same beautiful effects that these have.
