Three identical black 11×14 Brooklyn frames, matted to 8×10, climbing the stair one step at a time — the same minimal progression as our 12×18 trio, in the smaller size for a shorter run or a narrower wall. About 39 inches along the wall and 28 inches of rise.
Brooklyn is our slim brushed-aluminum frame: a crisp 0.3-inch edge that reads modern against a stair wall and disappears around a black-and-white print. Three frames, three nails, and a line that follows the handrail.
Hanging note: set each frame's centre about 60 inches above the tread beneath it and step them at the stair's own rise — the plan gives the spacing for a standard 7-inch riser.
