Create natural-looking stems using 3 gauges of self-sticking tape. With stems, it's easy to gather and arrange various flowers and leaves into a beautiful floral spray. This set includes 8- 20-gauge, 8- 22-gauge and 16- 26-gauge wires and 30 yards of 1/2-inch wide florist tape. The lower the number, the stronger the wire; the higher the number, the more flexible.
