Silk

A picture shows specially hand manufactured silk clothes tinted with colors specially extract from some natural resources, the procedure was performed by a famous engineer with methods of ancient technology who has a longer tradition of Yoshioka Dojo(Japanese Fencing training school).
Though I suggest her not to disturb him by visiting his workshop so often, because he is busy working on reproducing national treasures, she turns a deaf ear to me and has been allowed to take these jewel-like marvelous clothes without any hesitation? As my opinion, such kind of talented engineer has a tendency to be sensitive some time and difficulty to getting along with another persons well.
This is why I suggested her to be refrain from visiting his workshop like a excursions or going on a pleasure jaunt.
