The 2" Blender Brush makes it possible now, as never before, to achieve all of those soft, delicate, subtle areas so often found in landscapes and seascapes: skies with soft, wispy clouds, the misty areas at the base of mountains, background trees and waterfalls. In seascapes, the 2" Blender is especially effective for blending the transparency or "eye" of the large wave. The Bob Ross landscape brushes are special brushes made from natural bristles and shaped according to Bob's very precise specifications for the Bob Ross Wet-on-Wet Technique.
