Brush techniques

The governing concept is brush pressure: when the hand applies light pressure, the bristles bend and spread less, so only a smaller amount of the brush touches the paper. This produces a thinner, lighter stroke. Therefore, option B is correct. Heavy pressure generally creates a broader mark, while the other choices do not describe the normal result of changing pressure.

The governing concept is directional brushwork. A stroke moving horizontally, vertically, diagonally, or in a curve can suggest different movement, texture, emphasis, and form, even when the brush and colour remain unchanged. Thus option C is correct because direction affects the line’s movement and visual effect. It does not alter the paper size, the colour’s name, or the brush’s price.

The governing concept is proper tool maintenance. If paint remains in the bristles, it can dry, harden, spread the hairs apart, and permanently change the brush’s shape. Washing the brush soon after use keeps the bristles flexible and ready for controlled strokes, so option D is correct. Cleaning does not make the brush heavier, darken paint, or shorten its handle.

The governing concept is safe brush care after washing. First reshape the damp bristles so they return to their intended point or edge, then place the brush flat to dry. This helps water leave the brush without forcing the bristles to bend. Option B is therefore correct. Bending the tip, using strong heat, or leaving the brush in paint can deform, burn, or damage it.

The governing concept is identifying the parts of a painting brush. The bristles are the bundle of soft or firm hairs at the working end; they hold and transfer paint to the surface. Therefore, option D is correct. A palette is used to hold or mix colour, a canvas is a painting surface, and a frame supports or surrounds an artwork. None of those names refers to the hair bundle.

The governing concept is the structure of a painting brush. A ferrule is the metal sleeve fitted between the bristle bundle and the handle; it holds the bristles securely and helps maintain the brush’s shape. Thus option A is correct. A nib is normally a writing point, while a clip and a pin are not the standard names for this joining component. Recognising the ferrule helps in identifying and caring for brush parts.

The governing concept is recognising the functions of brush parts. The handle is the portion designed to be held, allowing the artist to guide pressure, direction, and movement while painting. Therefore, option B is correct. Bristles apply the colour, the ferrule joins the bristles to the handle, and a palette holds or mixes colour. These parts work together but are not the hand-held section.

The governing concept is continuity of hand movement in brushwork. For a long flowing stroke, the hand should travel smoothly along the planned path with steady pressure and without unnecessary pauses. This allows the line to remain connected and expressive, so option C is correct. Frequent stops create broken marks, shaking reduces control, and movement without direction does not produce a deliberate flowing stroke.

The governing concept is using brush shape to create texture. A worn or spread brush has uneven bristles, so it makes broken, irregular marks rather than a precise controlled line. Those marks can suggest grass, foliage, dry texture, or rough surfaces; therefore option D is correct. Such a brush is not suitable for measuring paper, and it is less useful for a very fine straight line than a well-shaped brush.

The governing concept is pressure control in brushwork. When a loaded brush is pressed, its hairs spread and produce a wider mark; as the pressure is gradually released and the brush is lifted, the mark narrows to a pointed end. This wide-to-pointed movement resembles a leaf and can be completed in one stroke. Leaving the brush in water, cutting paper, or drying paint does not create this controlled painted shape.

The governing concept is matching brush movement to the desired form. Rotating the brush around a small central area deposits colour in a rounded pattern, so it is useful for representing the centre of a flower. A straight wall would need a broad, even stroke, a long rope would need an elongated line, and a triangular roof would require angled strokes rather than a circular mark.

The governing concept is that different parts of a brush create different marks. Although the face of a flat brush makes broad strokes, its narrow edge contacts the surface over a small width and can produce a relatively thin, straight line when moved steadily. It cannot tear paper or press clay, and a very large circle is not the specific use of its edge. Therefore, option C is correct.

The governing concept is surface area and mark width in brushwork. Using the complete broad face of a flat brush places many bristles on the surface at once, producing a wide, comparatively even band of colour. This makes it useful for filling areas and creating broad coloured strokes. It is not a pencil sharpener or an eraser, and a full flat face is not used only for tiny dots. Thus, option D is correct.

The governing concept is wash application: colour is diluted and spread in a thin, transparent or semi-transparent layer, often over a comparatively broad area. This allows the paper or an underlying colour to influence the final appearance. A collage joins materials, modelling shapes a three-dimensional form, and carving removes material; none describes transparent brush application. Therefore, option A, wash, is the correct term.

The governing concept is repetition and directional movement in mark-making. When brush strokes are repeated along the same direction, the visible marks guide the eye and create a directional texture, suggesting movement, grain, hair, or a similar surface quality. This action does not randomly create circles, punch holes in the paper, or remove all colour. Hence, option C correctly describes the effect.

The governing concept is using directional marks to suggest natural texture. Short diagonal strokes resemble individual blades of grass because grass grows in many narrow, angled forms close together. A calm sky is usually shown with broad, smooth areas, a smooth wall with an even surface, and a round plate with a curved outline and controlled shading. Therefore, the stroke pattern in option D is the most suitable representation.

The governing concept is representing surface texture through appropriate marks. Tree bark is irregular, uneven, and often broken into ridges and patches, so broken, rough strokes can imitate its visual character more convincingly than a uniform mark. A smooth wash hides texture, one large dot provides too little structural information, and a white area does not describe bark. Thus, option A is the suitable stroke.

The governing concept is the function of painting tools. A palette is a smooth surface used to place separate colours and mix them into the required shade before the brush touches the painting. Therefore, option C is correct. A palette does not dry brushes, hang pictures, or cut paper; those actions require different tools or methods.

The governing concept is brush preparation and paint flow. A slightly moist brush allows water-based paint to be picked up smoothly and distributed more evenly across the surface. Thus, option D is correct. Slight moisture is useful, but excessive water can dilute the colour, cause drips, and reduce control. The other options describe no normal benefit of moistening a brush.

The governing concept is control of brush movement during colour application. Coordinating the hand, wrist, pressure, and brush direction helps the painter keep colour inside the drawn boundary. Therefore, option A is correct. Too much water may make paint run, closing the eyes removes visual guidance, and excessive speed usually makes accuracy more difficult rather than improving it.

The governing concept is precision in brushwork. Applying slow, controlled strokes lets the painter guide the brush along the intended edge, maintain even pressure, and correct direction before paint spreads beyond the boundary. Therefore, option B is correct. A very wet brush, dripping paint, or randomly spread bristles makes the edge less predictable and usually produces an untidy result.

The governing concept is progressive practice in brush control. Practising straight and curved lines on paper develops hand–brush coordination, pressure control, direction, and confidence before the learner attempts detailed forms. Thus, option C is correct. A complex painting is too advanced for a first exercise, moving without paint gives limited feedback, and cutting a brush damages the tool instead of building skill.

The governing concept is matching a brush stroke to the form being represented. A curved stroke follows rounded contours and is therefore suitable for making a soft, rounded shape such as a flower petal. Option D is correct. A straight road, square window, and flat horizon are primarily described by straight or level edges, so they are less suitable examples of curved-stroke use.

The governing concept is maintaining colour purity during painting. Washing or thoroughly rinsing the brush removes traces of the previous pigment, so the next colour remains close to its intended hue and brightness. Therefore, option A is correct. Cleaning does not shorten the brush, polish the paper, or add physical weight to the painting; its purpose is to prevent unwanted colour contamination.

The governing concept is contamination caused by residual pigment. If traces of the previous colour remain in the bristles, they transfer into the new paint and change its hue, brightness, or saturation. Consequently, the new colour may look muddy or altered, making option B correct. It will not necessarily become transparent, white, or completely dry; those outcomes do not follow from colour residue.
