Phoenix 6616S4 Flat Brushes for Watercolour Washes
An even wash — a sky without blotches, a smooth water surface or an unbroken background — is difficult to paint with a round brush. You need a wide flat brush that holds plenty of thinned paint and releases it evenly. That’s what the Phoenix 6616S4 set is designed for; the manufacturer’s catalogue describes it as a watercolour wash set. The three flat brushes have natural weasel hair and short black handles, and the packaging states that they can be used with watercolour and acrylic.
What’s in the set
- short flat (bright) no. 12: 1.5 cm hair, 17.5 cm handle with ferrule — smaller areas, edges, windows and buildings
- flat no. 18: 1.9 cm hair, 18.5 cm handle with ferrule — washes, skies and water
- short flat (bright) no. 24: 2.1 cm hair, 18.5 cm handle with ferrule — large areas, backgrounds and wetting paper
How to use the set
Use the widest brush, no. 24, for large areas and to wet the paper before painting wet-on-wet. Flat no. 18 is suited to skies and water, while short flat no. 12 is for smaller areas and crisp edges. The set complements round watercolour brushes, which you can use to paint shapes and details.
You’ll find paints for these brushes in the watercolour paint collection, and the full brand range in the Phoenix collection.
