SOFT
Used with light body or thin paints, when more control and a fine point or edge
is desired and for blending, glazing and varnishing where little or no brush
mark is desired.
MEDIUM
Will retain shape with good control along with the ability to hold more paint
when using medium to heavier body paints.
STIFF
Closest to bristle in function with the ability to push and manipulate thicker
paints, and to scumble and blend paint on the canvas.
