So after ages of painstaking engineering and planning, I finally finished my first pair of fiber optic fairy wings. They are run by two AA batteries hidden in a concealed padded pocket in the back.
These wings have the same features as the rest of my wings with hinged fabric panels and slide clips for the ribbons.
For my first attempt, I am pleased with how they turned out.
These babies really glow: these pictures were taken in the dark.
