When working on a painting, it’s important to switch up your brushes and not use the same brush for the whole thing. I know, you get your favorite brush and everything else is not as much fun to use, but by changing up your brushes (and therefore brush strokes), it will create a sense of dynamism in your painting that one brush couldn’t do on its own. You might even learn to love another style of brush for what it does differently than others!
This is a great series on YouTube I just discovered by Jill Poyerd Fine Art. It’s interesting to see how brushstrokes have evolved over the course of art history and the styles that emerged from them.
