LINE QUALITY

Zigzag

Curved

Diagonal

Vertical


Vertical lines run up and down. They never lean. Lines of this type seem to be standing at attention. Artists use vertical lines to show strength and permanence.

Picture the soaring lines of a skyscraper (Figure 72).


Diagonal lines are straight lines that slant. Lines of this type suggest a sense of movement and excitement. They seem to be rising or falling. Diagonal lines are used to give a sense of movement.


Curved lines arelines that changedirection little bylittle. Wiggly linesare made up of twoor more curves. Spirals and circles also begin with curved lines. Like diagonals, curved lines express movement, but in a more graceful way (Figure 73).



Zigzag lines are formed by joining several diagonals that move in different directions.

The diagonals form sharp angles that make lines change direction suddenly. Zigzag lines create confusion. They suggest action or nervous excitement (Figure 74).


 

Think about the crease in a pair of freshly ironed trousers. Would you describe this

line as smooth or rough? How about a line made with chalk? Smoothness, roughness, thickness, and thinness each represent a different line quality.This quality is the unique character of any line.

How a line appears depends on several factors. These include:

The tool used. Acrayon produces a slightly ragged line. Apaintbrush dipped in ink produces a line that narrows and trails off.

The pressure of the artists hand. Pressing down on a tool creates a thicker line.

Using less pressure creates a thinner line. How would you describe the quality of

the lines in Figure 75?Are the lines smooth or rough? Are they thick or thin?
