Acustomer comes into your shop carrying a gorgeous oval bowl. it’s very large and low, and has a pale gray crackled glaze. he tells you it’s a bonsai container that he picked up during a trip to japan. he asks you to make an arrangement of fresh flowers that will be placed in this bowl. the arrangement will then be displayed in the foyer of his business for a celebration that will take place there next week. the furnishings in the foyer are very modern. the bowl will be placed on a counter, so the arrangement will be visible from both sides. the customer says that the colors in the foyer are black, white, and gray. he wants an artistic arrangement that suits the bowl. after he leaves your shop, you decide that a parallel-systems floral design is just what this container needs.

b. a perfect line of massed chrysanthemums forming concentric circles of color

c. at least two parallel groups of upright flowering branches used as line materials
