It's hard to describe... Using a long piece of thread, I wrap one end several times around the index finger of one hand and the other hand around the thumb of the same hand. Then I place the thumb and index finger of other hand at other end (loop) and twist so that I now have something that looks like a bow with hands at either end.
I've since learned that I am doing it right and was getting the hair out at the roots. It doesn't take too much longer than having it done for me.
