One essay, one practice, once a week.

It goes out on Fridays, because Friday is when the week is done and the standing table is set. Each letter carries one essay from one of the three sections, one practice you can keep that week, and, once the shop opens, one object that carries the line. Nothing else. No news roundup, no launch countdown, no streak.

Subscribing also sends you the short form of the book, nine pages, so the letter has something to stand on. The link at the bottom of any letter ends it.
