Has anyone created Halloween gestures? I have some ideas.

Pumpkin - hands together finger tips touching, thumbs make the base, and
the index and rest make the D shape.

Witch - make a pointed hat with both hands and then a broom like you are
rowing a boat.

skeleton - move your shoulders up like a puppet with your arms dangling.

ghost - from the pumpkin gesture, just point your fingers down,
making two ghosts.

mummy - lips tight together and hold hands firmly by your sides

howl - tilt head up and pretend to howl or just howl

spider - have on hand crawl up the other arm very slowly , while showing
great fear oh no!! its getting closer!!!

vampire - show your teeth like you have long fangs, while moving your head
looking for some thing to drink

zombie - (look like one of my first period morning students!)

scared - hold your fingers close to your mouth as if you are biting your
nails in fear!!

bat - hold both wrists together to make a bird, but a bat has very fast
moves and erratic movement.
