Repetition is a form of shape design. Its main goals are to guide the eye throughout the artwork as well as give a somewhat calming effect. Repetition helps the eye to relax, it allows the viewer to look at something and only have to analyze it once. When you use many different shapes close to each other, your artwork might start to look a bit messy because it’s hard to tell what is what and why. Repetitive shapes have the power to guide the eye to the focal point as well, which turns it into a really powerful tool.
