A squirrel flat wash brush for soft coverage, glazing, and fluid broad strokes.
Series 6236 is another squirrel-hair brush in Isabey’s wash-focused family, and it is best understood as a flat companion to the 6235 wash line. Isabey brushes are known for quality natural hair and careful construction, and the series is positioned for artists who need soft, high-capacity brushes rather than point-heavy detail tools. A squirrel flat is especially useful when a painter wants a broad stroke with a gentle edge, such as glazing, large washes, or wet-in-wet work. Compared with sable flats, it will feel much softer and less springy; compared with synthetic flats, it will usually hold more fluid and release it more delicately. This makes it a strong choice for watercolour and loose, fluid techniques where softness and paint load matter more than rigidity. jacksonsart
What makes this brush special
The feel should be soft, expansive, and very fluid. The flat shape gives a more structured edge than a round wash brush, but the squirrel hair keeps the stroke gentle and evenly loaded. It will not snap back sharply, so the user gets a smooth, flowing response instead of a crisp rebound. That combination is excellent for large soft passages. tebbsgallery

How to care for your brush
Clean softly with lukewarm water and a mild brush soap, avoiding any rough handling of the hair. Because squirrel hair is delicate and soft, do not scrub hard or force the flat edge into a point. Reshape only lightly and store with the head protected so the flat profile remains intact. Never leave the brush standing in water, and allow it to dry completely before putting it away. greenandstone
