Lovely blog hannah! I like the photos quite a bit! Although I do have a question: How do you brew tea out in nature? I guess I'm wondering about how you get hot water in the middle of nowhere!
I use a camping stove (propane canister sort of setup, very portable and the flames arent affected by wind) with a lightweight camping kettle!
I did try a cast iron kettle for a while (heavy duty, not a tetsubin, about 4x thicker) but I had safety concerns as it was too heavy and I am often sitting on a slope etc so a lightweight steel one was a lot safer
I also used to take a few bottles of spring water with me too in the car both for boiling and cleaning.
The whole setup including about 3 sets of teaware fits in a small laundry basket in the boot/trunk of the car
