Smart Brush for Watercolour, Acrylic and Oil, Flat, Assorted Sizes

These are general-purpose studio brushes, built to work across watercolour, acrylic and oil rather than being specialised to one medium. The hair is set in a seamless metal ferrule on a lacquered wooden handle — the ferrule is the part that fails first on a cheap brush, so a well-crimped one matters more than it looks.

The shape of a brush decides what mark it can make, far more than its price does. Rinse it before the paint dries in the heel, reshape the tip with your fingers while it is still damp, and store it upright on its handle or lying flat — never standing on the hair, which bends it for good. Acrylic is the medium that kills brushes fastest: it sets hard inside the ferrule where you cannot see it.

A flat brush ends in a square edge: it lays broad even bands, cuts a clean straight line on its side, and covers ground fast. It is the shape for skies, backgrounds and anything architectural.
