Try using one brush in different ways to really get the most out of it.
Consider:
the brush load ,
the saturation,
the dryness,
the pressure,
the angles,
the pivot,
and the edges.
The angle of your handle to the paper also impacts the dispersion of paint across the surface.
I’m using my best seller The FLING! It’s smooth nylon bristles are rigid yet responsive, and they always remain splayed so it’s perfect for trees, grasses, splattering, and so much more! I use it in my oil, painting, for gouache, and for watercolor.
