Pro Tip 1/2
Visual Imagery
Use 'flutter' to describe a delicate or light movement you can picture, like petals in the breeze. Petals flutter to the ground in the gentle wind.
Pro Tip 2/2
Subtle Motion
Apply 'flutter' when the motion isn't forceful or intentional, but rather natural and subtle. A curtain fluttered softly by the open window.
