Buying guide
Choose a rigger, liner, or short detail brush
A branch that crosses the page and a tiny highlight in an eye both need a narrow mark. Decide whether you need to pull a continuous line or place a small mark that stops cleanly.
What to compare
Use a long head to pull a longer mark
Liners have long hairs that carry paint along a stroke. Look for this shape for stems, grasses, rigging, or a handwritten line. A nearby pointed round may be enough for a short stem that ends inside a petal.
Use a shorter head to place a small mark
A spotter is a compact detail shape. Its shorter hairs suit work such as a highlight, a small letter, or a row of dots. Compare the exposed bristle length if two brushes carry similarly small size labels.
Check whether one brush can do both jobs
A long round is a compromise when you need to switch from a larger mark to a fine line without swapping brushes. A dedicated liner and a short spotter still make sense when you do long stems and tiny controlled marks in the same piece.
Questions before buying
What should I buy for grass stems that keep breaking mid-stroke?
Compare a liner or rigger with longer bristles. Its head can carry more paint along a narrow mark than a tiny spotter.
Is a size 0 round interchangeable with a size 0 liner?
Check their head lengths and shapes. The small round can be useful for shorter marks while the liner is designed to pull a longer line.
Which brush is easier to control for a tiny dot?
A short spotter gives you a compact head for placing one small mark. Use a pointed round if you also need to vary the width of nearby strokes.
