------------------------ Cutting the Floss ------------------------ Floss should be cut about 18"-20" long, or twice that if the thread will be doubled for the loop method. Some people like to use one arm length when doubling. See section "2.12 How to Start the Thread" for more information about the loop method. Metallics, or any fiber with a very rough surface, should be cut somewhat shorter. It helps prevent fraying. Most people prefer to separate the floss into individual strands, and then recombine them. There is less twisting and knotting, and the stitches lie flatter. To separate a thread from the others, hold onto the top end of the thread between your thumb and forefinger. Pull down on it with the other thumb and forefinger, taking all the other threads with you. It looks like a knot will form, but have faith. Everything comes out just fine.
