The empty row is the one the chart was bought for

Three rows, seven columns each. TEETH is full — seven gold stars, one of them plainly drawn on in blue biro rather than stuck. SHOES ON has four stars and three empty cells. NO SHOUTING has none.

Only one row ever filled up, and it was the row that didn't need the chart in the first place.

Why keep the empty row instead of cropping it out?

Because the empty row is the half that reports something — it's the behaviour the chart was actually bought for.

TEETH filled up fast because brushing teeth was never really the problem; it's the row a child was already close to managing before any stars existed. NO SHOUTING stayed empty because that was the genuinely hard one, and a chart with only the easy row printed would be lying about what the whole exercise was for. The gap between a full row and an empty one is the actual result, not a blemish on it.

What does the biro star tell you that a real sticker doesn't?

That the system was already being gamed by somebody who couldn't yet read the rules they were bending.

A child too young to reliably print letters can still work out that a star in the box gets the same reaction as a stuck-on one, and draw their own. That's not cheating in any meaningful sense — it's an early, accurate read of what actually mattered to the adults watching the chart, which was the star appearing, not the mechanism that put it there. It's a different kind of chart from one kept about a dog or a cat, who cannot read it and never gamed it — this one is being filled in by both sides at once.

Is this a record of obedience or of something else?

A negotiation — the chart is where a household and a child settled on what counted as done.

A behaviour chart looks like a one-way instrument: adult sets rule, child complies, sticker appears. What it actually captures is closer to a running argument about what "done" means — whether a half-brushed set of teeth counts, whether shoes on with the laces still undone counts, whether a quiet sulk counts as not shouting. The chart is the paper trail of where those arguments landed each week.

Does the child get a say in whether this goes on a shirt?

Eventually, yes — the chart belongs to the family that made it, but the person on it grows into an opinion about what got printed of them.

Nothing about a home-made chart is licensed from anybody; it's the household's own record. The live question isn't permission, it's timing. Some children, looking back at a chart with an empty row on it, find it funny. Others find it exposing, particularly the row that stayed empty the longest. The better approach is asking once they're old enough to have a view, rather than guessing on their behalf either way.

Whose idea was the chart — the child's or the parent's?

Almost always the parent's, which is worth saying plainly rather than dressing the chart up as the child's own initiative.

That doesn't make it dishonest. A behaviour chart is an adult tool for making progress visible in a house where progress on a habit like not shouting is otherwise invisible week to week, the same way a household writes down the five steps of getting to bed because the order itself needs recording, not just the outcome. The child's real contribution here is the biro star — the one piece of the system that wasn't designed by anyone.

Did it keep working?

For almost every household, no — three weeks or so is the usual span before a chart like this stops getting checked.

That's not a failure worth hiding from the design. The chart did what it was going to do in the window it worked, and the fact that it stopped is part of what makes it accurate rather than aspirational — a version that pretended the system ran forever would be printing a hope, not a record like a household schedule kept for a while and then quietly abandoned.

Does it print well?

Yes — a grid with solid stars is a natural fit for a limited number of flat colours.

Seven columns and three rows read clearly at chest size as long as the grid lines stay simple and the stars stay a single solid shape rather than a detailed illustration. The one deliberate keeper is the biro star: reproduced in a slightly different tone from the gold ones, it stays legible as the odd one out — exactly the kind of small variation a handful of flat colours can carry without the print losing clarity.

How do I get one made?

Describe the chart at JustOG — the rows, which one filled up, and which one never did. 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 ever bought a new sheet of stickers once the biro trick was discovered.
