It’s great for all types of drawing styles and works beautifully with a dip pen or brush. With a brush, DANIEL SMITH Walnut Ink handles like a transparent watercolour with good layering and lifting capabilities in darker washes. The rich colour resembles traditional walnut-based inks, but will not fade. Walnut Ink is wonderful for adding warmth and historical character when painting over sketches done in permanent black ink, and by itself, it’s reminiscent of the aged ink drawings by Rembrandt and Da Vinci. When used with calligraphy pens, the Walnut Ink gives a beautiful, transparent, warm tone to lettering.
