01 / UNDERSTAND THE SHAPE
The long fibres act as a paint reservoir for continuous lines. How far one load goes depends on your paint and surface.
Fine strokes of different lengths add organic details and movement to your subject.
The head responds to changes in direction and pressure. A planned, steady movement helps with lettering and ornament.
02 / YOUR SIZE
Two narrow, long heads for flowing lines. Compare the 1.5 and 2 mm head measurements using your paint on the same surface.
Size 10/0 with a 1.5 mm head for fine twigs, thin grasses and delicate lines.
Your selection ✓ No. 12 mmSize 1 with a 2 mm head for slightly fuller lines and flowing lettering.
View size →The millimetre measurement describes the head size. Your painted mark results from angle, pressure, paint load and surface.
03 / FROM TOOL TO MARK
Plan its path, adjust the paint load and test the first stroke. Fluid paint and an even movement allow the long head to do its work.
Pick up paint evenly. Check that it flows without releasing a drop as soon as you touch down.
Preferably pull the brush behind your hand. Move your hand and forearm together when the stroke grows longer.
Reduce contact towards the end and lift off gently. Plan branches as separate, steady strokes.

04 / IN THE STUDIO
A long line feels alive when you guide its path deliberately. Try a wave, a short piece of lettering and a branch with a few twigs. The studio lesson shows long, fine lines and writing with the brush.

A different task, a different shape. These three models complement your brush and expand your possibilities.
06 / GOOD TO KNOW
At 1.5 mm, the 10/0 has the narrower of the two stocked heads. Size 1 measures 2 mm. The actual line results from angle, pressure, paint and surface; the head measurement is not a fixed stroke width.
An insufficient paint load, a thick mixture or an absorbent surface can interrupt the mark. Check the combination with a test stroke and reload evenly. There is no fixed distance per load.
Conventional oil paint cannot be adjusted with water; use an appropriate painting medium if needed. For acrylics, follow the paint manufacturer’s instructions. Water-mixable oils are a separate case.
Separate brushes are sensible for oils and water-based paints. This helps prevent residues and different cleaning methods from affecting your next paint mixture.
