MIDDLE or CENTER (flat hand
variation)
You can do the dominant handshape with either a flat hand or you can use a
middle finger bent forward from the large knuckle.
This sign is can be combined with DEAF to mean "Deaf Center."
MIDDLE:
Here is a lesser used variation of "middle." I wouldn't use this for
"center."
This version means more along the lines of "the middle of a series" or
"middle name."
