Enough thread. Enough room.
The landscape notebook experiment
I wanted a notebook wide enough for a walking route and short enough to balance on one knee. The first sketch looked simple, but a landscape shape changes the way a book behaves. The open pages have more leverage against the spine. A tight stitch that seems harmless in a narrow book can become quite noticeable here.
I folded a test section before cutting the rest of the paper. Opening and closing that little sample showed me which direction the sheets preferred to bend. I marked the useful direction in pencil on a scrap rather than trusting myself to remember. It was a minute of preparation that saved a much longer argument with the finished pages.
The exposed sewing took two attempts. On the first, I pulled each pass firmly because I wanted the spine to look neat. The result looked tidy and opened reluctantly. On the second, I kept the sections aligned but let the thread rest without forcing it. The difference was small in appearance and obvious in the hand.
The final book has indigo covers, an ochre thread, and enough room at the spine to lie comfortably on the table. The geometric drawing is a simplified view of signatures and sewing, intended to explain the parts rather than prescribe a binding method. My next change will be practical: a slightly tougher cover, because this notebook has already started going on walks.
