This cotton, cloth-covered floral wire is the finest millinery wire one can buy. One bundles contains 20 feet (6.1m) of 18 gauge spring green wire. The metal inside is galvanized and therefore will not rust! The tightly wrapped cotton will not unravel either, even if wet. So it is great for glueing or sugar flower work. Scott Clark Woolley of "Cakes By Design" uses this wire extensively for all his sugar art work because it is simply the most reliable wire out there. It comes in both white and green in these gauges: 18, 20, 22, 24, 26, 28, 30, 32 and 34 gauges.
