The Myonkkuri is helping!

i've always been somewhat confused when trying to imagine how most of the SFXs Tani Takeshi uses for his osa-yukkuri's would actually sound...i keep picturing the SFX in panel 4 sounding something like a rain stick...

It's a softer sound than I usually see it translated. It's more like a light gust of wind or the sound of fabric moving over fabric.
