Plying, from Sarah:
Sarah uses the cap from a spice bottle to keep her ply balanced. She starts plying by threading the end of one strand of yarn through one of the holes in the cap, so that each singles gets its own hole. Then she plies normally, and the cap keeps the tension on the strands even so that no little boucle sections form.
