Another member of the large brush family is the Round Foliage Brush. This brush can be used to create numerous fantastic effects such as clouds, foothills, trees and bushes. Using this brush with the other large brushes will save you time washing out the brushes and reduce paint consumption. The Bob Ross Landscape Brushes are special brushes made from a blend of natural and synthetic bristles and are shaped to Bob's very precise specifications for the Bob Ross wet-on-wet technique. Keep in mind that ordinary brushes are not the same and cannot achieve the same beautiful effects as these.
