According to CQ24, a 大海茶入 was used by Eisai when he got the “first” tea seeds to Japan

The shape of the 平棗 is the shadow of this 茶入.

If you put your pinky through the right eye, it becomes much easier. (You got to prevent it from turning, and then put it on the bottom).

For 休み, start as usual, but make the top / left one shorter. Then put the bottom / right one through for about 1 cm, tighten, then put the rest from left and right through the new eye.
