Sequence of Movement
The movement starts in the middle of the back by forming a "c" with the index fingers and thumbs of both hands, the index finger and thumb of each hand touching each other. Then move both hands outwards, indicating the horizontal lines of a rectangle, whereby the hand shapes do not change. When you reach the shoulder blades, the rectangle is closed by moving the index finger and thumb of the right and left hand each towards each other. Into the rectangle created, you tap with the fingertips from left to right. This is supposed to represent braille.
