Kazari (飾り) means “ornament” or “decoration”. This is anything in a shibari pattern that has no technical function. A typical example is the diamonds (hishi, 菱). Also, the creative “tucking away” of the nawajiri after the completion of a technical component is a kazari.
Excellent bakushi spontaneously create a creative and aesthetically pleasing kazari. At the same time, they interact with their partner. You can see how experienced someone is by how well both are done at the same time.
In order to learn this, experience is needed. The basic patterns and basic techniques must be understood and mastered. When a bakushi understands the logic of rope flow, spontaneous creativity also develops.
A shibari pattern always follows the same structure. With these decorations, you can vary these patterns and change them visually. Thus, from the same basic techniques always creates something new.
