Use the Calligraphy Angle to set the stitch angle for drawing Calligraphy 
.
The angle is initially set to 135 degrees, and can be varied continuously from 0 to 359 degrees. Enter the desired angle directly in the box before selecting Calligraphy. Alternatively, use the up and down buttons to change the angle at any time.
Use Q (counter-clockwise) and W (clockwise) while drawing Calligraphy to dynamically change the angle. Tap the Q or W key to change the angle by one degree. Hold the Q or W key to continuously change the angle.
