How can I create texture with Watercolour?

How you use your brush can add texture. If you work in a ‘dry brush’ technique, using less water, to leave more pigmented, scratchy marks. Alternatively, mediums add texture. Mix in granulation medium to give a mottled appearance to colours which would otherwise appear as a smooth wash or enhance a naturally granulating colour. Granulation medium can be used undiluted, instead of water, for a more pronounced effect. In addition, texture medium makes the dry surface of the colour rough, and Aquapasto medium gives watercolour a thicker, impasto quality.
