Review (5/5): Try this trick to easily use this great floss.
Have trouble holding this great floss? Try this: cut a piece about 14 inches long. Double it over then tie a simple overhand knot four to five inches down to form a loop slightly wider than your hand. Gently try to floss a tooth. Adjust the knot to an ideal size for you. The magic is that the knot is easily moved by separately pulling the ends. Once it's optimal tie a second knot and tease it until it sits on the first knot. They will now be locked into position. You can apply loads of force without deforming your loop.
