The idea behind shigumi is that the teishu only needs to make a single entrance with dougu. Not as far as Kumiawase, but still easier.

This is technically for older people (with weak or tired knees).

Do before chaki is out. (What does this statement mean? Where does it go?)

Preparation

Start with the hishaku and futaoki already out in decorated positions.

The preparation of the chawan/kensui (hereafter: unit). The standard chawan prep (chawan, chakin, chasen, chashaku) is placed on top of the kensui.

Temae

The unit is brought in with both hands (slightly bridging the kensui/chawan border for stability). With both hands, place the unit in the usual spot for the kensui.

(?) Move the futaoki and chasen to their proper positions. Bow.

With both hands, take the chawan, but place it with just the right hand (!?).

Grab the futaoki, rotate body,
