Its when you use your hands to burn the top and bottom, put your hand in front of you and put your fingers together and form a point at your middle finger. that is the *Ducks bill* and is used for the top of the head burn. Now round out your fingers a bet and you will see a more gentle curve * Ducks Ass* this is to give a more rounded base to a portrait .
