What mechanical method will Abby employ when creating a cascade floral arrangement?

In creating a cascade floral arrangement, using ribbon for hand-tying is particularly effective because it allows for flexibility and control in shaping the design. A cascade arrangement often features flowers and greenery that gracefully drape downward, and the hand-tying method enables the florist to secure stems while also allowing for natural movement and flow. This technique helps emphasize the cascading effect, making it visually striking.

In contrast, other methods like water tubes or oasis foam may restrict the arrangement's ability to achieve the desired cascading look. Water tubes are useful for providing hydration to individual stems but do not facilitate the overall structure of the arrangement. Oasis foam is typically used for more rigid arrangements, where stability and support are crucial, rather than for showcasing the fluidity of a cascade design. Glue for binding, while useful for securing materials, is not commonly used in cascade arrangements, as it can detract from the natural presentation and limit the florist's ability to adjust or reposition flowers as needed.
