Perhaps the most well-known of all the Bob Ross brushes, the 2" Background Brush is handy enough to create all of the effects that the 1" 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.
