WildFire beading thread is braided 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 on fingers. This knottable, supple cord is also great for multi-strand seed bead designs.
