my fan is fraying....urgh!!!
it's a nylon cloth, but what can i do to stop it from continuing to fray?
1.) Duct tape may look poor, but it works. Otherwise, you're best bet's probably putting a hem in at the edge, to stop the fraying. Investing in a silk fan is probably a good thing.
2.) Any art that works short sticks (Arnis, Yawara-jutsu) or flat weapons (Tessen-jutsu, Wushu Moon Crescent Blades) would work for a fan. If you're looking for form work, I recommend playing with the fan and choreographing your own. If you want combat principles, look at the striking surfaces of the fan, and think of how they could be used.
