I am frequently asked about brushes. When I am teaching brushes are a fundamental component of painting but I use them in my studio rarely. I think many artists, especially those just beginning their painting journey, think that there is a perfect brush for every task. I tend to think that you can make most brushes do what you need (with a few exceptions). So I tend to not spend much time worrying about what number or hair type I have. Of course softer brushes are better for thin applications and blending, and stiff brushes are better for thick paint and texture. Big brushes are better for washes and small ones are better for detail. But I can get a filbert and a round to make pretty much the same marks, and a flat brush makes great lines. So there is a lot of overlap. You don’t need dozens of brushes. But maybe that’s just me. I work mostly with knives anyway. When I do use a brush, my all purpose favorite is a medium soft synthetic flat. Here are a few examples of my most used brushes (when I use brushes at all).
