I spent two cold weeks last winter measuring the rooms people actually used after dinner: the corner beside the stove, the low table with tea rings, the patch of floor where a child kept returning with a book. The best interiors had almost nothing to prove. They kept one dark line underfoot and let the rest of the room exhale.
A line can protect without becoming a wall
The old lozenge teaches a useful restraint. It is not a logo, not a border, not a perfect diagram. Its broken charcoal path gives the eye a route across a pale field, then disappears into pile, shadow, and the ordinary weight of furniture.
Let the mark arrive like a remembered path: uneven, necessary, and quiet enough to live with.
