The clean arc on a potting bench is a body drawn by accident
A potting bench seen from above at the end of a session, with a swept arc cleared through the spilt compost by one forearm working back and forth — a shape nobody drew on purpose.

A potting bench, seen from directly above, right at the end of a session. Compost pushed aside in a heap. Nine pots filled, arranged in something close to a grid but not quite. Three empty ones tipped on their sides. A trowel laid down. And running through the middle of the spilt compost, a clean, curved, swept-clear arc.
Nobody drew that arc on purpose. A forearm did, going back and forth, without thinking about it once.
What is this actually a picture of?
The end of an ordinary session at a bench, not a staged one — the compost, the pots, the trowel, all left exactly where the work stopped.
Look at it from above and the whole session reads at once: what's been filled, what's still empty, where the mess is. It's a plan view of a task rather than a portrait of a person doing it, which is a different thing to put on a chest — nothing here is posed for the shirt.
Why is the swept arc the part worth looking at twice?
Because it's a body, drawn in negative, by somebody who wasn't trying to draw anything.
A forearm working compost back and forth across a bench clears the loose material out of its own reach and pushes it to the edges, and the boundary between cleared and uncleared is a curve — the exact radius of one person's arm from one elbow position. Nobody could sketch that curve from memory and get it right; it only exists because the motion actually happened.
What makes a good version of this design worth choosing over a tidier bench?
Keeping the grid of pots honestly uneven rather than squaring it up.
Nine pots in a perfect grid look staged, like a catalogue photograph. Nine pots roughly aligned, with two crowding each other and one set slightly apart, look like what they are — filled at speed by somebody who'll come back to finish the tray tomorrow. The three tipped empties matter for the same reason: a bench mid-task has unfinished business sitting on it, and tidying that away would be tidying away the actual subject.
Who owns the layout of a potting bench?
Nobody. A trowel, a heap of compost, a grid of terracotta pots and the particular sweep of one forearm belong to no maker and no brand — a scene like this is drawn fresh and stays that way.
What would need permission is a specific photograph this was copied from, if a real one exists and is the direct source rather than a loose likeness. Drawn from the general shape of how a bench actually looks after use, it's clear of that from the start.
Does the same idea work for a different bench, or a shared one?
The logic holds anywhere one person's motion leaves a mark nobody else would make the same way — a workbench, a kitchen counter mid-prep, a desk at the end of a long session.
What has to stay specific is the asymmetry: an arc swept by one right-handed forearm curves a different way to one swept by a left hand, and a bench two people share would show two overlapping arcs, not one clean one. A dibber's handle darkens in the same accidental way — neither design is inventing the mark, both are just choosing to notice it.
Isn't a messy bench a strange thing to want printed on a shirt?
Only if mess and evidence get treated as the same thing, and they aren't.
A bench with nothing on it says nothing happened here. This one says a specific amount happened, recently, by one person, and will happen again — the compost heap, the tipped pots and the trowel aren't clutter, they're a record of exactly where the session stopped. An empty trug carries the same argument from the opposite direction: what's missing is as informative as what's there.
Does it print well?
Yes — a flat plan view with a strong graphic shape at its centre holds up well at chest size.
Charcoal carries the compost, the pots and the trowel as hard-edged flat shapes; terracotta picks out the pots on their own so the eye can count them without hunting. Keep the swept arc as a clean, confident curve rather than a soft gradient — it's the one part of the design that has to read instantly, and a hard edge survives fabric far better than a blur does.
How do I get one made?
Describe the bench at JustOG — how full it is, how many pots are done, and where the sweep runs. 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.
A curve in the spilt compost, exactly the width of one arm's reach, and no other trace of who was standing there.
