ok, im trying to follow this head building tutorial i've got as far as the pic above but then it say:- Create the first loop at the corner of the mouth. Here, the outer row of polygons is connected is connected to the lower row with a single quad poloygon to create a ring... waz that mean then :-) I can guess its talking about joining the sides of the lips in sections but single quad polygon is that a new shape to join the ends together if so I've tried that and the new shapes edges just vanish.
I'm sure it makes sense and I probably just cant see the forest for the trees but my heads hurting now so I need assistance.

Ta!
