The idea
A cover for the notebook you already love. Sized for a standard pocket notebook (A6-ish, 9cm × 14cm) with elastic at the spine so you can swap the insert without retiring the cover. I built mine in 2014 and I am still using the same cover; the notebooks inside it have turned over thirty-one times.
The leather
Buttero from Conceria Walpier — an Italian veg-tan that darkens in warm oranges and reds. By year two yours will not look like mine; by year five it will look like nobody else’s.
The small things
Two inside pockets, one for a pen and one for the things you tuck into notebooks. No pen included. Bring your own; I have opinions about pens and am choosing not to share them.
