What is the goal of the tracing and layering technique in floral arrangements?

The goal of the tracing and layering technique in floral arrangements is to create depth through varying heights. This technique allows a designer to give the arrangement a more dynamic and full appearance by placing flowers and foliage at different levels. By varying the height of the materials used, the designer can create visual interest and texture, making the arrangement more engaging to the viewer. This technique enhances the overall composition and allows each element to stand out, contributing to a more balanced and harmonious design.

Stacking similar materials uniformly, which was selected as the answer, typically leads to a flatter appearance without the depth and dimension that layering offers. The other options focus on aspects like color contrast or emphasizing a single floral type, neither of which aligns with the primary goal of tracing and layering.
