Traditionally, watercolour is painted on specialized paper which comes in a range of weights and textures. Various painting methods are employed such as: wet on dry, wet into wet, glazing, line and wash and dry brush. Masking fluid is commonly used to create highlights, and special effects can be created with the aid of salt, wax, sponging and spattering. Other drawing and painting media can be combined with watercolour, including pencils, inks, pastels and acrylics. Many watercolour techniques have been adapted over time for use with acrylic paints, and are part of the repertoire of today’s decorative artists.
