Perhaps the most well-known of all the Bob Ross brushes, the 2-inch Background Brush is handy enough to create all of the effects that the 1-inch brush is used for, yet large enough to cover large areas very rapidly. The Bob Ross landscape brushes are special brushes made from a blend of natural and synthetic bristles and shaped according to Bob's very precise specifications for the Bob Ross Wet-on-Wet Technique. Remember, ordinary brushes are not the same and can't create the same beautiful effects these will.
