I would suggest you find a stationary store and feel it. Rub it between your fingers, pick up a quill and write on it until you find one that you enjoy. Experiment until your fingertips are numb, then return to do it again.
And then I would suggest letting someone write on you if you do not want to write on them. A quill scratches, every letter etched into skin like diamonds into glass, but a small brush and thick paint? It remains cool until it dries and blowing over it creates a response unlike any other.
My hands are journey loving travelers, mapping out the road between love and lust and divine ecstasy. Learn what your hands are for, they belong to you, not to any other. Let not your mind interfere with their direction.
I would not allow inexpert hands to change her, not even my own.
