The morning of 1 May.
I was just about to head to Mulgi Drift to take photographs. Raassilla RX circuit, cars, dust, noise and a whole day with a camera. Before setting off, I stopped at a petrol station in Tartu. An ordinary moment: the car was filling up, my thoughts were already at the track, and the clock was telling me things were about to get busy.
Then an email arrived.
A small team of women had made it into the President’s Education Hackathon with their idea for a school leader’s data assistant. They needed shirts. Not “we should make some one day” shirts. They needed them now. The event was already coming up on 8 and 9 May.
The question was simple: does Blacksunset make custom T-shirts?
The answer was simple too: yes, but within that timeframe only if we stuck to black or white T-shirts. We regularly keep those in stock. Everything else moves at the pace of the German warehouse, where nobody is particularly concerned that people in Estonia discovered they needed shirts a week before the President’s hackathon.
An honest system. No fairy tales for sale.
But first, I needed to see the design.
When the design arrives on paper
A few minutes later, a photograph arrived.
White paper. Blue pen. Front on the left. Back on the right.
On the front: DIQU. A small hand-drawn face. Underneath, a question: “Can your school talk to its data?”
On the back: “Presidendi haridushäkaton 2026”, Estonian for “President’s Education Hackathon 2026”.
This was not an agency brand book. Not a vector file. Not a PDF with the correct margins and colour codes.
It was an idea.
And honestly, that was enough.
Shirts do not always have to begin in Illustrator. Sometimes they start with a picture shared during a petrol-station stop: one idea, one name and one sentence on paper that says exactly why the team is going on stage.
DIQU’s idea was to help school leaders talk to their data. Not to design another “we are innovative” shirt that gets worn once and pushed to the back of a wardrobe. They had a specific idea, a specific event and a specific need to stand out.
That is the most important part of a custom team shirt.
Not the size of the logo.
The reason.
The first visuals during a fuel stop
I quickly put together the first visuals.
Not to create an art exhibition. To help the customer see whether the idea worked on a shirt. A black T-shirt. White print. A simple, unpolished front, just like the original drawing. A clean back with slightly larger text, so it would be readable on stage and in photographs.
The customer chose the version with “2026” underneath the hackathon text on the back. Their only request was to make the text on the back a little bigger.
The right adjustment.
Because an event shirt does not exist only in front of a mirror. It exists on stage, in group pictures, in front of an audience, in press photographs, on phone screens and later in some article where someone zooms in to work out what it says.
If the text is too small, you have made a nice file, not a good shirt.
Why the black shirt worked
A black shirt was the right choice here.
First, practically: it was in stock and could be made within the deadline.
Second, visually: the black background kept the hand-drawn graphics clear. The white line looked like a marker on a board. Simple, understandable, a little school-like, a little technological, but not sterile.
Third, the team looked like a team. Not in the corporate “we were given company polo shirts” sense, but like their own team. It was their drawing. Their question. Their own small, unusual character.
This is where merch becomes more useful than a piece of clothing.
It gives a team a visible identity.
On Monday, the drawing came to life on a shirt
By Monday, the production files were ready. The text on the back was larger. Five black unisex T-shirts went into production.
By that evening, the shirts had been handed over to the customer.
A drawing on paper had become a real shirt.
It sounds simpler than it is. With a rush order, printing is only part of the problem. The other part is the speed of decisions. The files need to be prepared. The design needs to be clean enough. Sizes need to be confirmed. The product needs to be available. The customer needs to reply quickly. And someone has to say when a nice idea becomes a bad idea for printing.
In this case, everything lined up.
Not because the process was “inspiring”. Because decisions were made quickly.
The President’s Education Hackathon and DIQU
On 8 and 9 May, the President’s Education Hackathon took place in Tallinn. Teams spent 36 hours working on AI-based solutions for Estonian schools.
DIQU developed a solution to help school leaders make more data-informed decisions with AI. In practical terms: how to bring information scattered across different systems into one view, so a school leader does not have to search ten spreadsheets, folders and who knows where else for the full picture.
That is a good problem to tackle.
Not an “AI, do something cool” problem. A real working-life problem. The data exists, but the different sources do not talk to each other. A school leader needs to make a decision, but the information is fragmented. Then a shirt asks: “Can your school talk to its data?”
That exact sentence is what makes the shirt work.
It does not explain everything. It opens a door.
Then another email arrived
After the hackathon, the customer emailed.
Not a long report. A few lines.
They wrote that the shirts had appeared in a photo with the President and their project was €2,000 better off. They had received plenty of attention, which was the goal. The shirts were very good quality and the team liked them.
This is where the value of a custom shirt becomes quite concrete.
A shirt did not win the hackathon. That took a good idea, a strong team and a convincing presentation. Clothing does not build a prototype or win over a jury.
But a shirt helps a team be seen.
And visibility matters.
Especially when there are many teams, many ideas and a lot of noise in the room, and everyone has roughly the same amount of time to be remembered.
A good team shirt does not have to shout
What I liked most about this project was that the design did not try too hard to look “professional”.
It was not overdesigned. No gradient. No endless AI sparkle. None of the blue-and-purple technology froth that fills the internet at the moment.
There was a black shirt. A white drawing. One name. One question. One event.
It worked because it was theirs.
B2B merch often falls into the same trap: make the logo too large, add too many words and end up with a garment nobody wears by choice. An advertisement forced to live on a T-shirt.
The DIQU shirts were different. More a sign of belonging to the team than an advertising poster.
And that is why people noticed them.
What this order can teach us
If you need shirts for a company, event, team, training session or hackathon, three things matter more than simply requesting a price:
1. Be clear about the purpose.
Does the shirt need to be visible on stage, readable in photographs, suitable for everyday wear or just a one-off souvenir? Those call for different design decisions.
2. Do not wait for a perfect file.
A good design can start with a drawing, a screenshot or a single sentence. What matters is having the idea. The technical side can be sorted out if the time and printing method allow it.
3. A rush order needs quick answers.
If the event is next week, every “let’s discuss it some more” uses up real time. Size, colour, quantity, print placement and text need to be confirmed quickly. Otherwise, production is no longer the problem. Decision-making is.
DIQU handled that part well.
The design came quickly. The feedback came quickly. The sizes came quickly. And that is why the shirts got made.
A hand-drawn idea on a real stage
I like projects like this.
Not because they are big. Five shirts is hardly a huge production run.
But it is a good example of why custom merch exists. Not just for the logo. Not just so people “have something to wear”. So that, at a particular moment, in a particular room, a team looks like a team.
On 1 May, it was on paper.
A few days later, it was on a black shirt.
Then on stage.
At the President’s Education Hackathon.
A pretty good journey for an idea drawn with a blue pen.

Frequently asked questions
Does Blacksunset make custom T-shirts?
Yes. Blacksunset makes custom T-shirts, sweatshirts, tote bags and other merch for companies, teams and events. For urgent orders, the choice depends on which products are immediately in stock.
Does the design have to be a finished vector file?
No. The initial idea can also be a photograph, a drawing, a screenshot or text. A print-ready production file still needs to be prepared before production starts.
How quickly can custom shirts be made?
That depends on the quantity, product, print and stock availability. Black and white basic T-shirts are easier for urgent orders because they are usually available sooner.
Can I order a small number of team shirts?
Yes, smaller quantities are possible if the design and product are suitable for printing. Ask for a quote with your specific quantity, deadline and design.
