Use FireLine SMOKE GREY 8LB 0.007 Diameter (125yards) for any beading project:

This beading thread is very strong and extremely flexible. It is made from polyethylene, one of the strongest fibers ever made. Fireline is a favorite beading thread of many beaders who create intricate designs requiring multiple passes. It is very durable and feels and works better than many other stringing materials. It does not stretch, knots easily, and will pass through a #12 beading needle.
