A diamond on a flowchart is an argument

An empty flowchart still tells you where the decisions are — three diamonds, seven boxes, and two paths that cross rather than run in parallel.

A cream tee pinned flat to a wall, printed on the back with a completely blank flowchart — one start box branching through three decision diamonds and seven rectangles, arrows linking them, two paths crossing near the middle, every shape left empty

One box at the top. Three diamonds under it, each one splitting the line in two. Seven rectangles hanging off the branches, and two of the arrows cross on the way down.

Nothing on the shirt says what any of it means, and the chart is still readable.

What is a chart like this actually for?

Telling a newcomer where to start when a body of work was not built in one straight line.

A long-running story that picked up a prequel, a side story, a film that sits sideways to the main run, or a reprint that shuffled the original release — any of these leaves a gap between "the order it appeared in" and "the order that makes sense to a first-time viewer," the same gap that gets drawn as two columns of numbers wired together with crossing lines when the confusion is about sequence rather than entry point. The chart is somebody closing that gap for a stranger.

Why does a diamond appear on the chart at all?

Because a rectangle is a step and a diamond is a question, and the two shapes are doing different jobs.

A rectangle says: watch this next. A diamond says: it depends on something about you — whether you've already seen the side story, whether you care about the film, whether you want the version with the extra chapter folded back in. The moment a diamond shows up, the chart is admitting that one line can't cover everyone reading it.

What makes the crossing paths the interesting part?

They're the one place a straightforward "just watch it in order" argument breaks down completely.

A chart with no crossings is really just a numbered list wearing a diagram's clothes. Two paths crossing means the routes genuinely interleave — a viewer following the left branch ends up watching something the right-branch viewer saw three steps earlier, and there's no way to draw that as a straight column. The cross is the diagram doing work a sentence couldn't.

Can I use the actual title and box labels from a real one?

No — a specific work's structure, and the copy describing it, belongs to whoever made or wrote about it, and plenty of these charts already circulate under somebody's name.

The diamond-and-rectangle grammar itself isn't owned by anybody. Flowcharts predate every fandom that uses them, and an empty one is arguably more useful on a shirt than a filled one — it reads as what it is, a decision tree, rather than as a spoiler for a franchise you haven't started.

Does this only work for something you watch?

No. Anything assembled by more than one hand, in more than one order, earns a chart like this — a reading list with prerequisite chapters, a course built on branching electives, an archive of case files somebody eventually had to sort for the person after them.

The shape asks the same question regardless of the subject: where do you actually begin, given that "the beginning" and "the first thing made" turned out to be two different places. It's a close relative of the grid that marks which instalments to skip once you're already in — one chart is about the door, the other is about what happens once you're through it.

Isn't a blank chart just a shape with no content?

That's the whole trick of it, and it's why the empty version prints better than a filled one would.

Take the labels off any well-made flowchart and the geometry alone still tells you where the hard choices sit — count the diamonds, look at where lines cross, and you know how contested the order is before you read a single word. The timeline that splits and never rejoins its own branches works on the same trust: a shape can carry an argument that a blank label never gets the chance to spell out.

Does it print well?

Very — line art with hard corners and consistent stroke width is close to the easiest thing there is to put on cotton.

Keep every box the same weight and every arrow the same thickness; the eye reads flowcharts by comparing shapes, and any wobble in the linework reads as noise rather than style. One accent colour on a single diamond, if you want it, is enough to mark where the real decision sits without turning the rest into clutter. Single-colour line art is the most forgiving register on fabric for exactly this reason.

How do I get one made?

Describe the branching decision at JustOG — how many diamonds, how many rectangles, and where you want the paths to cross. 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.

Somebody sat with a franchise's whole publication history and drew this so a stranger wouldn't have to.

Upload the image you already made, see it on the real garment, and get the physical piece. Made to order, no minimum.
