backpack
BACKPACK:
This sign uses a double motion. You hold "C" hands over your shoulders and bring them down twice so that the backs of your thumbs touch the area between your neck and your shoulders. The sign starts about an inch away from the body, touches, comes up, and comes down again.
BACKPACK variations:
There are several variations of this sign.
Some people use "C" hands (or modified large "G" hands") to show the placement of the front straps of the backpack.
Others use "A" hands and do a thumping motion on their chest.
Still others mime putting on a "shoulder bag."
