It's drawn empty because empty is where it spends its life
A wooden trug drawn three-quarters from above with nothing in it, its thin boards shown individually and its handle worn pale at the centre from years of one grip.

An empty trug, seen three-quarters from above. The thin overlapping boards of its body are drawn one by one rather than as a single curved shape. The handle is worn pale exactly at its centre. Underneath, on one board, a pencilled mark — 2G — is half rubbed away.
Nothing is in it. That's not an oversight. That's the trug most of the time.
What is this actually a drawing of?
A trug at rest, not a trug at work — the state it's in for most of the hours it exists.
A garden trug is built from thin boards of wood, steamed and bent round a frame rather than carved or moulded from one piece, which is why the diagram draws the boards as separate overlapping strips instead of a single smooth bowl. That construction is what makes it light enough to carry all afternoon and shallow enough that whatever goes in it doesn't crush whatever's underneath. Full, it's a container. Empty, on a hook or a bench, it's just this shape — which is most of its life.
Why is the handle worn pale specifically at the centre?
Because one hand, gripping the same span of wood in the same place, for years, will lighten it faster than the sun or the weather ever could.
The handle is worn pale where a palm closes around it, and nowhere else, in the same way that a dibber goes darker exactly where four fingers sit rather than fading evenly along its shaft. Nobody sanded that patch on purpose. It's the residue of every trip from the bed to the bench, added up in one place, and it's the most specific thing on the object.
What makes a good version of this design?
Leaving it empty, and drawing the boards as the separate steamed strips they actually are rather than smoothing the body into one clean curve.
A full trug reads as a picture of vegetables, which is a different subject with a different point. An empty one, with its construction left visible, reads as a picture of the carrying itself — the tool doing its actual job, which is being light and being there, not holding anything in particular at the moment it's drawn.
Who owns the shape of a trug, or a mark like 2G?
Nobody owns the shape. A trug's basic form — steamed boards round a frame, a bowed handle — is a traditional pattern of construction, not any single maker's design.
A specific workshop's own stamped mark, a branded capacity rating or a maker's printed label belongs to that workshop, licensable the ordinary way if a real one is the point of the shirt. The 2G on this trug is invented rather than a real maker's rating, which is exactly why it needs nobody's permission to print.
Does the same idea work for a basket, a bag or any other carrying object?
Any container that's mostly seen full works differently when it's drawn empty — a wire basket, a seed tray stack, a wheelbarrow tipped up against a wall.
What most of them share with a trug is that emptiness reveals the construction rather than hiding it under contents, and the wear pattern is usually still there to draw even with nothing inside. A plait of onions is the opposite case worth noting — that object only exists once it's full, because the crop is its own container. A trug is a container with nothing built in, which is exactly what makes drawing it empty tell you something true.
Isn't an empty trug just a less interesting picture than a full one?
Only if the point of the shirt is the vegetables rather than the tool, and here it isn't.
A full trug is mostly about whatever's sitting in it — the marrow, the beans, the picture changes completely depending on the harvest. An empty one is stable: the same worn handle and the same overlapping boards regardless of the season, which is a steadier thing to put on a shirt than a snapshot of one particular afternoon's picking. It's the same reasoning behind drawing a potting bench at the end of a session rather than mid-task — what's left once the work has moved on says more than the work itself would have.
Does it print well?
Yes — thin overlapping boards and a simple bowed handle are exactly the kind of hard-edged repeated shape that survives fabric cleanly.
Charcoal against sand keeps every board line distinct without needing shading to separate them; the faint 2G mark can sit as a single light line, worn rather than crisp, since it's meant to read as pencil losing a fight with the outdoors. Keep the handle's pale patch as one flat lighter tone rather than a soft gradient — the wear is a fact about the object, not a lighting effect.
How do I get one made?
Describe your trug at JustOG — how worn the handle should look, and whether to keep a mark on one of the boards. Pick a direction, drag the crop frame, see it composited on the real garment, and it's made to order and shipped.
