Principle of Repetition
The principle of repetition simply means the reusing of the same or similar elements throughout your design. Repetition of certain design elements in a design will bring a clear sense of unity, consistency, and cohesiveness.
REPETITION is the use of similar or connected pictorial elements. For example, similar shapes, colours or lines that are used more than once
REPETITION can be regular or irregular and even or uneven.
REPETITION can be in the form of RADIATION where the repeated elements spread out from a central point.
REPETITION may be in the form of GRADATION where the repeated elements slowly become smaller or larger.
Repetition works with pattern to make the artwork seem active.
The repetition of elements of design creates unity within the artwork. Patterns often occur in nature, and artists use similar repeated motifs to create pattern in their work.
Principle of Parallelism
“Elements that are parallel to each other are seen as more related than elements not parallel to each other.”
Lines are often interpreted as pointing or moving in some direction. Parallel lines are seen as either pointing or moving in the same direction and are thus related.
It should be noted that for parallelism to be perceived, the lines can also be curves or shapes, though with the latter the shapes should be somewhat line-like in order for them to appear parallel.
