Brush techniques

A broad flat brush is suitable for a flat background because its wide edge covers more surface with each stroke and can distribute paint in an even direction. Option D is correct, especially when the brush is loaded consistently and strokes are kept orderly. A thin liner and a small pointed brush are designed for narrow lines and details, not large areas. A hard-toothed comb may create texture, but it cannot normally produce a smooth, uniform background.

The governing idea of dry-brush technique is limited paint and little moisture on the brush. Because the bristles do not cover the surface continuously, they leave broken, irregular marks that suggest rough textures such as wood, grass, stone, or aged surfaces. A perfectly even wash requires more fluid paint, while transparency and wetting paper are not the main purposes of dry brushing.

The governing concept is control of paint viscosity and brush size. Excess water makes acrylic paint flow beyond the intended edge, while a broad brush is difficult to control for small marks. Working on a wet background can increase spreading. Option D is correct because thicker paint, less water, a small brush, and a dry surface provide better control for fine details.

The governing concept is directional mark-making. Water is organised along a mostly horizontal surface, so light horizontal and broken strokes suggest ripples, reflected light, and interrupted images without making the surface rigid. Option B is correct. Vertical lines, random circular marks, or a thick black border do not describe the calm horizontal movement of water and its reflections effectively.

The governing concept is texture-specific mark-making. Tree bark is uneven, ridged, and broken rather than perfectly smooth, so relatively dry paint and irregular rough strokes can suggest its cracks, grooves, and coarse surface. Option C is correct. A flat wash creates an even area, very wet spreading removes control, and isolated white dots do not describe bark structure.

A flat brush has a broad face and a narrow edge. When the broad face is placed against the surface, more bristles touch it and produce a wider band. Turning the brush so that its edge contacts the surface reduces the contact width and creates a thin line. Thus, changing the brush angle changes the effective contact area. Paper colour, palette size, and water-container size do not determine the stroke width.

In a round-brush press-and-lift stroke, pressing spreads the flexible bristles and increases the contact area, producing a broad mark. Gradually reducing pressure while lifting brings the bristles together toward their tip, so the mark narrows and ends in a pointed taper. This movement is useful for leaves, petals, and curved decorative forms. The stroke is not equally thick, merely a dot, or colourless.

The governing concept is the relationship between brush moisture, surface texture, and broken marks. In dry-brush work, only a small amount of paint is carried by the bristles, so it touches mainly the raised areas of rough paper and leaves gaps over the depressions. This produces a broken, textured appearance. Therefore, option C is correct; the paper does not release water, the bristles do not cut it, and complete absorption would not explain the visible texture.

The governing concept of an even wash is consistent paint loading combined with smooth, continuous brush movement. If each stroke carries nearly the same sufficient amount of diluted colour, the layer remains visually uniform and does not show sudden pale gaps or dark pools. Therefore, option A is correct. Unequal loading creates patchiness, a completely dry brush cannot lay an even wash, and adding extra paint only at the end produces an uneven finish.

The governing concept is maintaining a wet edge during a continuous wash. When the next stroke overlaps or joins the still-moist edge, the liquid colour flows together and the boundary becomes a smooth transition. If the first edge dries before the next stroke is added, a visible hard band or stripe can form. Therefore, option B is correct; this practice is not intended to thicken paint, shorten the brush, or polish the paper.

The governing concept of a graded wash is gradual change in value, usually from darker to lighter. An artist achieves this by progressively reducing pigment concentration or increasing the proportion of water as the strokes continue. Hence option C is correct. Changing the brush handle, paper length, or frame width does not alter the colour value and therefore cannot by itself create a graded wash.

The governing concept is water control in a paper wash. When excess water remains on the surface, gravity and uneven absorption can make the liquid collect in small areas. As it dries, pigment may move toward the edges and leave blooms, back-runs, or irregular patches. Therefore, option D is correct. Excess water does not make bristles grow, turn paint into metal, or transform paper into stone; those choices do not describe a painting effect.

The governing design concept is rhythm, which is created when visual elements repeat with a regular or progressive pattern. Repeating similar brush strokes at measured intervals guides the viewer’s eye and creates visual movement, so option A is correct. Completely unrelated marks lack continuity, erasing colour removes the painted rhythm, and a single stroke cannot establish repetition or a sustained pattern.

The governing concept is suggesting texture through grouped marks rather than copying every individual object. In dabbing, the brush is touched or pressed repeatedly to make small, varied spots that visually combine into foliage clusters. Thus option B is correct. Long straight lines do not naturally suggest leafy masses, a smooth wash lacks the broken texture of leaves, and cutting the paper is not a brush-painting technique.

The governing concept is atmospheric perspective: distant forms usually appear less detailed, softer, and lower in contrast than foreground forms. Therefore, short, light, and less detailed strokes suggest faraway grass effectively, making option C correct. Very thick, sharp, dark, or square marks attract attention and imply a nearby, strongly defined surface. Circular marks alone also do not communicate the fine, reduced texture of distant grass.

The governing concept is depth through contrast and selective detail. Foreground objects are made clearer by using stronger values, more defined marks, and visible directional structure. Applying some dark, distinct diagonal strokes suggests individual blades and increases the sense of nearness, so option D is correct. Erasing marks or using only water removes definition, while directionless strokes do not convincingly describe the growth pattern of grass.

The governing concept is that brush shape controls the marks produced on a surface. A fan brush has bristles spread in a thin, broad arrangement, so one stroke can create several delicate, parallel marks. This makes it suitable for hair, grass and soft foliage textures. A liner is better for precise lines, while paper cutting and spreading clay are unrelated to this brush.

The governing concept is matching a brush’s structure with the required stroke. A liner brush has long, narrow bristles that can carry a small reservoir of paint and release it gradually while the hand moves. This supports a flowing, continuous thin line, such as a branch or decorative curve. Handle weight, absence of bristles and dry-paint-only use do not explain its function.

The governing concept is identifying painting tools by the shape of their bristles. A filbert brush is relatively flat like a flat brush, but its end curves into a rounded tip rather than forming a sharp square corner. This combination allows soft edges and useful petal-like marks. The other choices compare unrelated tools and do not describe the filbert’s characteristic form.

The governing concept is the relationship between grip and mark-making. Holding the brush near the far end of the handle increases the distance between the hand and the bristles, reducing minute finger control and allowing a broader arm movement. The result is usually freer, looser and more expressive strokes. A close grip is more suitable for rigid precision; paint quantity and dot formation do not follow automatically from this grip.

The governing concept is that a closer grip improves control over small movements. The ferrule is the metal or connecting part near the bristles; holding the brush there shortens the effective lever and lets the fingers guide the tip more precisely. This is useful for tiny lines, contours and details. It does not dry paint, change the brush’s length or make every stroke broad, so option C is correct.

The governing concept is proper brush maintenance. Paint that dries between bristles can force them apart, so the suitable remedy is to clean the brush with the appropriate medium, rinse it safely, and gently reshape the bristles before storing it. Applying more pressure worsens the spreading, cutting damages the brush, and leaving it in paint can weaken the bristles and handle. Thus option D is correct.

The governing concept is value, meaning the lightness or darkness of a colour. In water-based painting, adding more water or using less pigment creates a lighter, more transparent value, while using more concentrated paint creates a darker value. Therefore changing the water-to-paint ratio can produce several values of one colour. New paper, a painted handle or merely changing brushes does not change the colour value by itself.

Opacity means that the paint hides or covers the surface beneath it. Using less water and enough concentrated paint places more pigment in each stroke, so the layer appears solid and opaque; therefore, option C is correct. A large amount of water makes paint transparent, an empty brush leaves little colour, and wet paper usually spreads and weakens the mark rather than making it opaque.

Crosshatching is a linear shading and texturing method formed by placing one set of strokes across another set. Drawing lines in two directions that intersect builds a denser network and can create darker values, so option D is correct. Dots do not form a hatch pattern, one isolated direction is simple hatching, and washing the paper is unrelated to brush texture.
