For bead weaving, stringing, and other needs, FireLine braided thread is a wonderful option. FireLine is a pre-waxed and braided cord made of highly durable material. It has been noted by many as the strongest fiber per diameter ever created. Since it's so strong, it's a great choice for using with crystal beads, as the crystals won't cut the thread. It also won't tangle or fray easily, nor does it stretch, giving you designs that last. It knots easily, and will pass through a #12 beading needle.
