Beadalon WildFire beading thread features strength and durability with a smooth, thermally bonded coating to create a superior stringing product that cannot be pierced with a needle. Super strong, waterproof, and near zero-stretch, this cord will not fray at the ends, which makes it easy to thread through a needle. WildFire is also Colorfast: the color will not come-off onto your fingers like some other cords. This knottable, supple cord is also great for multi-strand seed bead designs using a bead spinner.
