Which brushes best to use when laying a water colour wash?
Good quality sable makes the perfect water colour brush. A size 10 Series 7 is the best, it carries more water and gives the best control. Alternatives for large washes are the 2″ Sceptre Gold II flat wash brushes (sable/synthetic) or 1″ Artists’ Water Colour Sable one strokes or a Cotman mop brush. It is best to wet the paper before starting as this gives more time to graduate or control the colour. Always make enough of the wash before starting.
