Which arrangement technique uses both natural and man-made materials in creative ways?

The technique that utilizes both natural and man-made materials in creative and innovative ways is interpretive design. This style is known for its flexibility and emphasis on personal expression, allowing the designer to experiment with various textures, forms, and colors. Interpretive design stands apart by encouraging the incorporation of unconventional elements alongside traditional floral components, leading to unique arrangements that often represent abstract concepts or emotions. This approach is more avant-garde, allowing for an imaginative fusion of different materials, whether they are organic or synthetic.

The other techniques generally adhere to specific guidelines or styles that focus more on tradition or established aesthetic principles rather than on creativity and experimentation. These traditional methods often emphasize symmetry, shape, and balance drawn from history, making them less suitable for the use of various materials in a freeform manner.
