A line is a mark on a surface used with other lines to create a shape. Lines are very important during drawing and painting. They are used to define edges, decorate, and create shadow or space. A line has the quality of being thin or thick, delicate or bold, depending on what is used in making it. There are also different types of lines. There are vertical lines, horizontal lines, diagonal lines and rhythmic lines, which may be wavy, spiral, scrolls or loops.


Examples of lines are:

Thin line Thick line

Vertical line Horizontal line

Diagonal line Spiral line

Wavy line Loop

2. Form: Form is the visible appearance of a thing as it relates to the surrounding space. It is the external outline of an object. So, form is what something looks like.

Forms are of three dimensions and thus can be measured by height, width and depth. In drawing, form is also defined by light and shade. It also helps us to describe an object well.

There are two main kinds of forms.

a) Regular form – which refers to definite forms representing known objects and shapes.

b) Irregular form – refers to strange forms not associated with any known object or shape.

3. Value:  Value is the artist’s term for how dark or light a work or art is, starting from black colour to white. Darker colours are said to be lower in value while lighter colours are said to be higher in value.

4. Texture:

Texture is the surface quality of an object or a work of art. This is determined by the artist that produced such work. There are two types of texture:

a) Tactile texture: This is the actual surface of an object that can be touched.

b) Visual texture: This is our view of a surface texture as seen in a photograph.
