The Sign "Window"

Where

and how you sign is as important at the actual hand-shape of your sign. Signs are usually created in a "window" from your head to your torso. There are few exceptions to this rule. Using this window allows people who are communicating to regard each other’s faces, as they would if they were speaking verbally. Using areas outside of this window is distracting, impractical, and not a natural way to communicate.
