Daniel Burleigh Parkhurst, The Painter in Oil
“ For only the silkiest of bristle will do good work in a very small brush, and then the temptation is to use a sable, which should be resisted. Why you should avoid using the sable as a rule is that it will make the painting too "slick" and edgy. There is a looseness that is a quality to prize. All the hardness, flatness, and rigidity that are desirable you can get [Pg 28] with the bristle brush. When you work too much with sables, the overworking brings a waxy and woodeny surface, which is against all the qualities of atmosphere and luminosity, and of freshness and freedom of touch. ”
