The best watercolour brushes are traditionally made from sable, which comes in a variety of different hairs such as kolinsky, squirrel and goat. These brushes types can also be made from synthetic materials, which are a great alternative. They are used by artists to apply soft, flexible paint strokes with precise control. At Cass Art, we stock brushes from Winsor & Newton, Da Vinci, Pro Arte, Daler Rowney and Princeton, each offering a great selection of brushes to suite all levels and needs.
