[Andrew Craig-Bennett]

Answering my own post, and not having found the lowering hitch in Brion's book*, I would say:

Having stopped the standing part to the hauling part, preferably with a racking, but by grasping them together if you are singlehanded, pull the fall through the chair bridle to form a loop.

Pass the loop over your head and shoulders and make it long enough to go over your feet.

Pick up the loop with a foot and bring it up outside the bridle.

Haul taut; you should have a hitch on the bridle with the fall leading up; lift the fall to slack off, drop it to stop.

Comments?

Edited to add: Practice this six inches off the deck, first.

* Quite possibly because Brion thinks the lowering hitch is unsafe.
