How is wire used to support flower stems in a corsage?

Using wire to support flower stems in a corsage is primarily done by inserting the wire through the stem. This technique helps to provide the necessary stability for the flowers, ensuring they maintain their position and shape throughout the duration of wear. When wire is threaded through the stem, it acts as a backbone, allowing for better control over the placement and arrangement of the blooms. This method also helps to prevent the stems from breaking or bending, which can happen during handling or wear.

The other options do not provide the same level of support. Wrapping the wire around the stem can offer some reinforcement, but it does not stabilize the stem throughout, which could lead to a less secure arrangement. Attaching wire to the base of the flower might hold the flowers in place initially, but without integration into the stem, it lacks the necessary support. Intertwining wire with leaves might embellish the design but does not directly contribute to the structural integrity of the flower stems themselves.
