Flameworked glass is hand wound onto 18 gauage, 4 inch long, copper wire. Glass is twisted while still hot to create a unique headpin. Blue twist is between 24mm - 30mm long. Extra long length of wire allows you extra wire to wrap or string on more beads. As with all my glass, it is kiln annealed to ensure strength and durability. Use in combination with Cindy Gimbrone focal beads.
