DIY 形の良いエコバッグ 手ぬぐい2本で TENUGUI remake easy to make
[ 形の良いエコバッグ 手ぬぐい2本で - Good form eco bag with 2 tenugui]
Takes a couple of views to follow the sewing directions. Seems doable. Or one could use any fabric of choice of about 33 x 90 cm.
Geez, if I correctly understood Todoroki=san’s instructions in a previous forum thread. A tenugui is also a kind of cook utensil. Well, sort of. The instructions appears to be - dampen the rice in the stream, wrap the rice inside a dampened tenugui. Then bury the tenugui in the ground, place a stone over the hole the rice is buried in (as a lid), build your wood fire on top of the stone. No time was given, but I’d guess about 20 minutes or so.

Carry your rice home in the DIY bag, then cook the rice inside a tenugui.
