Which is NOT a step in creating a geometric design style?

Creating a geometric design style in floral arrangement emphasizes structure, form, and often a level of minimalism that highlights the interplay of shapes. The focus is primarily on the main components that establish the foundational design, which typically includes skeleton flowers to outline the shape, as well as a clear mental visualization of the piece throughout the arrangement process.

In geometric designs, additional elements, such as secondary flowers and foliage, are indeed integrated into the primary structure to enhance the visual impact while maintaining the geometric aesthetic. However, the addition of decorative ribbons and bows is not a characteristic step in forming this type of arrangement. Geometric designs tend to prioritize clean lines and shapes, relying on the natural beauty of the flowers rather than embellishments that may detract from the intended form and structure. Hence, the use of decorative ribbons and bows does not align with the principles of geometric design, making this step inappropriate in the context of the given question.
