Flower wire is a thin, flexible wire used primarily in floral arrangements and crafts. It comes in various gauges, with thinner wires being more pliable and suitable for delicate flowers, while thicker wires provide more support for heavier blooms. This wire is often used to strengthen stems, create structures for arrangements, or attach flowers to other materials. It can also be colored or coated to blend in with the floral design, making it a versatile tool for both professional florists and hobbyists alike.
