Why a steady temperature matters more than the perfect one, how much humidity a cork needs, light, vibration and smells, what to do without a real cellar, how to check the room and why every cellar needs a book.
Why it's the larvae and not the moths that eat your jumpers, where they hide, how freezing and cleaning deal with them, what traps and lavender can and can't do, and how we store wool so they don't come back.
The questions to ask before a guest arrives, why the bed comes first, temperature, darkness and quiet, the practical things nobody packs (plugs and Wi-Fi included), the bathroom, the small welcome and the last walk through the room.
