The sign for "grandmother"
is made by touching your chin with the thumb of your dominant hand, as when
signing "mother."
The dominant hand should be open. Move your hand forward in two small arches.
Note: Many people just move the hand forward without the arches.
GRANDMA:
Remember, there are two "right" ways to do this. One is just to use
to use two small arcs. The other is to use a single large arching
motion.
