How to hold the fan

There are several schools (Kisen-Ryu, Miyako-On-Ryu, Towa-Ryu, Misen-Ryu, etc) in Tosenkyo, so they have own rules, scoring, and etiquette. But most of them hold the fan with the same manner.
This is not defined so strictly, so you can modify as you like.

Please relax your hand, and make your thumb up. Put the opened fan at its pivot on your forefinger like this.
Your thumb should support the end of the fan not to drop from your hand.
