This ball is on a 6″ diameter Styrofoam ball. The kimekomi design in fabric is based on S8 division and the temari design with thread and yarn is based on a S16 division.
The color palette for this ball started as just neutrals with tans, greys and black with gold, but the green snuck in with the little green dots in the spirals on one of the fabrics. Green needed to be the accent color so green yarn was introduced, but the green yarn has a multicolored metallic thread running through it. So this yarn opened the door for the cream colored yarn with the same multicolored metallic thread in it too.
The original plan to use only the variegated grey and tan yarn would have produced a dull and uninteresting ball.
The north and south poles where the marking threads intersect create an interesting spoke design that looked unfinished. By adding the gold star design at the poles, it visually and literally ties the groups of threads together. To balance the gold at the poles, add interest to the equator or obi, and to bundle the crossing threads together neatly, gold thread was added to the obi ribbon.
By using a kimekomi base for a temari design, this allowed for changes in the background by having blocks of two alternating colors show through the open spaces rather than a solid color background. This changes how the thread/yarn colors on the top interact with the background. This means there are more design opportunities with being able to have a background other than a solid one.
