S-LON FIRE: This is a pre-waxed, braided bead thread consisting of gel-spun polyethylene, which is known as the strongest fiber, per diameter, ever created. It has an unbelievably high tensile strength and is recommended for various bead weaving and jewelry making projects. DETAILS: Our S-Lon Fire is 8lb. test and comes in a crystal-clear color. The cord measures .007” (.17mm) in diameter. The 50 yards are wound on a spool that is secured with a clear plastic clip. Keep your thread secure and organized. EASY FINISH: Because this is a super strong material, we recommend using sharp, precise scissors for cutting the string. However, the thread can also be burned instead of snipping. A thread burner is easier to use and more precise. This method seals the ends, which prevents frayed edges or split ends. VERSATILE: Originally used by fisherman as a high-quality fishing line, this thread took off in the jewelry making world. It can be threaded on a needle and used for stringing or bead weaving. The thread does not stretch, or tangle and the strength of the cord is essential when working with heavier beads and findings.
