The gap stayed after the reason for it left
A bedroom door drawn mid-swing in gold line on grey, hinge left, one measured gap on the right and a wedge of light spilling through it.

One door, drawn in gold line on grey, hinge on the left. It isn't shut and it isn't open — swung just far enough to leave a gap on the right, and through that gap one wedge of light spills out and widens toward the floor. No text, no border, nothing either side of it.
The door used to get closed all the way. At some point it stopped, and it never went back.
Why print the gap instead of the door shut, or wide open?
Because the gap is the actual habit, and neither of the other two states is true to what happens at night now.
A shut door was the old rule — full privacy, full quiet, checked once and left alone. A wide-open one would just be a room with no door at all. What's printed is the settled-on middle: pushed to, never latched, close enough to keep the draught and the hallway light out of the child's eyes but not so far that a hand has to touch the handle to look in. That specific angle is the whole point.
Why does the habit outlast the reason it started?
Because a body that has done something every night for years doesn't audit whether it's still needed — it just keeps doing it.
The gap probably started as checking on a much younger child: is the breathing steady, has a blanket come off, is the room too warm. Years on, the checking stops being necessary and the door stays cracked anyway. Nobody decided to keep doing it. The hand just never learned the new instruction, because no one ever gave it one.
How wide should the gap actually be drawn?
Narrow — a hand's width, not a doorway. Too wide and it reads as a door left open by accident; too narrow and the wedge of light disappears and the whole point of drawing it is lost.
The measurement matters more than it looks like it should. A door open a foot is a different object to a door open two inches — one is an invitation, the other is an old reflex nobody's thought about since. The print only works at the second width, the same restraint that keeps a line-art print from turning into a decoration: one deliberate, specific gap, not a generalised "ajar."
Whose design is this, and does it need anyone's permission?
Yours. An invented door and an invented wedge of light carry no maker's mark, no floor plan anybody could recognise as their own — there's nothing here to license.
The only judgement call is how identifiable to make the room behind it. Some people want the exact hinge, the exact handle, the door from one specific house; others would rather it stay generic enough that it could be anyone's landing. Either is fine. Nothing about this print requires the room to be recognisable for the habit it's recording to still be true.
How is this different from a door left ajar for somebody who's unwell?
The habit looks the same from across a hallway, but the reason has already ended here, and that's the whole subject.
An ajar door kept for somebody needing to be heard through the night is still doing its job every time it's checked. This one isn't checking anything anymore — it's a gap that used to have a purpose and got kept out of muscle memory once the purpose was gone. Same angle, same wedge of light, a completely different reason for existing.
Isn't a few inches of open door too small a thing to put on a shirt?
No smaller than most of what actually ends up printed this way. The size of the gesture was never what made it worth keeping — it's that nobody decided to keep it on purpose.
Most of what a parent actually changes about themselves is this scale: a door not quite shut, a step skipped on a particular stair, a light left on down a hallway. None of it would survive being told out loud as a decision. Drawn as one measured gap and one wedge of light, it holds.
Does it print well?
Yes — a single ink on a flat garment colour is exactly what a hairline elevation drawing wants. Two-line woodcut linework at this weight survives fabric better than almost any shaded style, because there's no gradient to lose.
Keep the palette to the two inks already in the print: the darker line for the door and wall, the brighter one for the light itself. Anything more starts competing with the wedge, which is the one part of the drawing doing the actual work.
How do I get one made?
Describe the door at JustOG — which side the hinge is on, how wide the gap actually is, and what colour the light should be. 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.
Nobody's checked on anyone through that gap in years. The door still doesn't shut.
