Time for one more mug of tea, then it's off to take some more photos of Cosmos fields. Very popular flower here in Japan, and there are huge fields of them in bloom all over!
Yes, a simple cloth bag would be perfect. Though I don't think I'd count on it working for that long. I'd set 6 months or so as the upper limit if your water has very much in the way of off elements. (Chlorine, or worse, chloramine are both significant contaminants.)
Finished up my pot of Keemun Xian Zhen.
