Watercolor brushes are specifically designed to hold a large amount of water, which is essential for creating the delicate washes and transparent effects that are characteristic of watercolor painting. The best brushes for watercolor painting are made from natural fibers, such as sable, squirrel, or goat hair. These fibers are soft and absorbent, and they allow the paint to flow smoothly and evenly. Synthetic fibers can also be used for watercolor painting, but they are not as soft or absorbent as natural fibers, and they can sometimes leave brushstrokes in the paint.
The shape of the brush also affects the way that the paint is applied. Round brushes are the most versatile and can be used for a variety of techniques. Flat brushes are good for creating washes and backgrounds, and they can also be used to create sharp lines. Filbert brushes are a combination of round and flat brushes, and they are good for creating both washes and lines. The size of the brush also affects the way that the paint is applied. Smaller brushes are good for detail work, while larger brushes are good for creating washes and backgrounds.
