This container of Super-Lon (S-Lon) cord features 12 bobbins of extra-heavy #18 twisted nylon multi-filament cord in a variety of cool winter colors. 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.
