NONE:
Form "O" hands and hold them out in front of you palms facing mostly
toward each other and a
little bit forward. Then quickly move your hands forward and shake your head
"no" once.
This sign can also be done with one hand.
As
I'm doing it here, the sign is almost identical to a casual version of
TEACH.



Here is another example of me signing "none."
Note that the hands move forward and a bit toward the outside.
