One stair gets skipped every time, and nobody asks why
A flight of stairs, drawn as a section, with one tread left empty instead of filled — a private rule reported exactly as it's followed.

A flight of stairs, drawn as a clean side-on section in bone against a rust tee. Eleven treads rise left to right, each filled in solid — except one, near the top, which is left as an empty outline. Nothing marks it, points at it, or explains it.
That step gets stepped over every single time it's climbed, going up and going down, and the house has quietly learned which one it is.
Why leave the step as an empty outline instead of marking it some other way?
Because an arrow or a label would be an explanation, and there isn't one to give.
An arrow says "this one, because." A cross says "this one is wrong." An outline, left unfilled while every other tread is solid, says that this tread is different from the rest — which is what's actually known about it. The print reports the pattern; it doesn't reach for a reason it doesn't have.
What makes a technical drawing like this the right register for a private rule?
Keeping the section plain, accurate and unadorned — the same drawing style an architect would use for an ordinary flight of stairs, applied to this specific one without embellishment.
A softer, more illustrated staircase would put a mood on the print that the rule itself doesn't carry. This isn't a cosy image of a household stair; it's a precise record of eleven treads, one of which behaves differently from the other ten. Technical, plain line work keeps the print true to the actual observation rather than dressing it up as a scene.
Whose rule is this to print?
The household's, and specifically the one person in it who follows it — nobody else set this rule, and nobody else could license it, because it isn't a design borrowed from anywhere.
There's no artwork or mark being reproduced here, just an architectural drawing convention applied to a real staircase, and that drawing style belongs to no single firm or designer. What's actually being printed is an observation, made by the household, about a pattern that's held for as long as anyone's been paying attention to it.
Does this work for other rules a child follows without explaining them?
Yes — any private, exactly-repeated rule works the same way this one does, whether it involves a staircase or something else entirely.
A five-step bedtime sequence that has to happen in order is the same shape of thing: a private system, enforced with total consistency, that nobody outside the house was ever consulted on. So is a route where every railing along the way has to be touched, or a garment that has to be cut a particular way before it's acceptable to wear. What's printed in every case is the pattern itself, not an account of where it came from.
Is it worth printing a rule that doesn't come with a reason attached?
Yes — the consistency is the content, and it doesn't need a reason behind it to be worth recording accurately.
The step has been skipped on the way up and the way down, in a hurry and not in a hurry, for as long as this has been noticed. That kind of exactness, held without anyone asking for it or explaining it, is already the whole subject of the print. It reports what's true about the stairs; it isn't the print's job to account for it, and it doesn't try to.
Whoever climbs those stairs after the print exists will still step over the same tread, print or no print. The shirt doesn't change the rule. It just puts down, in bone on rust, that the rule was real and exact enough to draw a section of the actual staircase around it.
Does it print well?
Yes — a clean section drawing in one flat colour is about as reliable a print as a technical image gets, since every line is doing structural work rather than decorative work.
Bone on rust holds the contrast at any size, and because the treads are simple rectangles, the design survives being scaled down without losing the one detail that matters: which tread is left open. Keep the line weight consistent across all eleven treads so the empty one reads by its fill, not by a heavier outline that would turn it back into a marked step.
How do I get one made?
Describe the stairs at JustOG — how many treads, and which one gets skipped. Pick a direction, drag the crop frame, see it composited on the real garment, and it's made to order and shipped.
Designs other people have published are in the shop.
Tonight, on the way up, the same tread stayed empty.
