WildFire: beading thread is made with a new synthetic material called Spectra; features the strength and durability of DandyLine with a smooth, thermally bonded coating, to create a superior stringing product that cannot be pierced with a needle. Super strong, waterproof, and zero-stretch, this cord will not fray at the ends which makes it easy to thread through a needle. This knottable, supple cord is also great for multi-strand seed bead designs using the Spin-N-Bead. Made in USA by Beadalon.
