Available in a variety of colors, Super-Lon (S-Lon) cord is perfect for a wide variety of designs. Each bobbin contains extra-heavy #18 twisted nylon multi-filament cord. S-Lon is great for stringing, bead crochet and micro-macramé jewelry. It is similar in weight and texture to upholstery thread and avoids stretching. Each spool contains approximately 77 yards of nylon cord that will fit through a size 12 beading needle.
