= an ongoing t-shirt competition, lets users submit t-shirt designs which the Threadless community can vote on for a period of seven days. The Threadless team picks t-shirts to be printed among the top scoring designs and sells these in their online shop. Not every user may get to wear his or her own design, but all the t-shirts are user-designed. 
Description from the Openeur blog at http://www.openeur.com/blog/en/2006/12/15/threadless/
"The success of the American shirt community Threadless is one of the most exciting stories in the movement of Open Innovation. Threadless has succeeded in rallying a very creative and vital community round them, pooling almost any working steps and risks on its users. The business model is as simple as evident: there are thousands of designers on the web who are willing to distribute their creations to as many people as possible. Threadless provides the platform for a permanent competition on designs.
Designers have the possibility to publish blueprints for shirts on Threadless. The community is able to rate them over a certain period of time and the blueprints with the most positive votes are subsequently produced by the company. The rights are passed to Threadless and the designer gets 2.000 dollars in return. In order to honor the merits of designers his or her name is printed on the label on the inside of the shirt. The number of needed shirts is calculated on the basis of experiences and estimated in correlation to registered votes. Thus sales can be backed and the risk for Threadless is relatively small.
It’s the community stupid!
Threadless has managed it as well as few other services to let the own community feel to be part of the project. There are several programs encouraging communication and interaction within the community. Users who take a picture of themselves in a Threadless shirt and afterwards upload it on Threadless get credits for which they can buy shirts again. Furthermore there exists an internal affiliate-system rewarding recommendations. Thereby the user’s identification with Threadless is strengthened also increasing the demand for other products. The sales of the company having about 20 employees at the moment are estimated on 18 million dollars this year. By 6.5 million shirts sold a year and a yield on sales of approximately 35 percent there stay respectable earnings left." (http://www.openeur.com/blog/en/2006/12/15/threadless/)
From Inc. magazine:
"Threadless, he explained, ran design competitions on an online social network. Members of the network submitted their ideas for T-shirts -- hundreds each week -- and then voted on which ones they liked best. Hundreds of thousands of people were using the site as a kind of community center, where they blogged, chatted about designs, socialized with their fellow enthusiasts -- and bought a ton of shirts at $15 each. Revenue was growing 500 percent a year, despite the fact that the company had never advertised, employed no professional designers, used no modeling agency or fashion photographers, had no sales force, and enjoyed no retail distribution. As result, costs were low, margins were above 30 percent, and -- because community members told them precisely which shirts to make -- every product eventually sold out. Nickell's company had never produced a flop.
Nickell is at the vanguard of a new innovation model that is quietly reshaping a host of industries. Whether it's called user innovation, crowdsourcing, or open source, it means drastically rethinking your relationship with your customers. "Threadless completely blurs that line of who is a producer and who is a consumer," says Karim Lakhani, a professor at the Harvard Business School. "The customers end up playing a critical role across all its operations: idea generation, marketing, sales forecasting. All that has been distributed."

"Nickell had no such vision as he put the finishing touches on a T-shirt design in late 2000. It was for the New Media Underground festival, an informal gathering of Web designers in London. He had no intention of attending the event, but he cared about it deeply. At the time, Nickell was 20 years old, living in a tiny Chicago apartment. He spent his days on the sales floor at CompUSA; at night, he was a talented if unenthusiastic part-time student at the Illinois Institute of Art. Though his girlfriend visited him each weekend, he had few close friends.
When he wasn't working or studying, Nickell was tinkering with Web design, a hobby he indulged in on Dreamless.org, an Internet forum for illustrators and programmers. He would spend hours at a time cruising the forum, talking with his online friends and engaging in a pastime called Photoshop tennis. In it, designers pass digital photographs back and forth and challenge one another to manipulate the images in the most outrageous way possible.
Nickell's design for the New Media Underground festival -- three lines of gray text that mimicked the layout of the Dreamless website -- was an entry for a contest that the festival's organizers were holding online. The design was simple and not quite pretty. But it was strikingly clever -- a physical representation of their digital community. The Dreamless members agreed. Nickell won the contest.
In concrete terms, this accomplishment meant exactly nothing: He got no money or even a copy of his winning shirt. But the experience was exhilarating. Dreamless members spent a lot of time batting ideas back and forth, but their creations rarely made it out of the digital realm. Suddenly, Nickell had an idea: What if the best designs were printed on T-shirts and sold in the real world? He suggested as much to Jacob DeHart, one of a handful of friends he had met on Dreamless. DeHart, a student at Purdue University, loved the idea, and each pitched in $500 -- enough to pay a lawyer to set up the business and print the first round of shirts.
Nickell and DeHart held their first contest in November 2000. They asked the designers on Dreamless to submit their best work and to pick their favorites. The grand prize: two free shirts and the promise that any proceeds would be reinvested in future contests. They called the competition Threadless, a play on thread -- either a clothing item or a discussion topic on an online forum. In all, they printed two dozen copies of five shirts out of slightly fewer than 100 submissions with in-joke titles like "Evil Mother F---ing Web Design" and "Dead Sexy Designer." The shirts went on sale in January 2001 for $12 each and sold out quickly. In the months that followed, Nickell and DeHart ran regular competitions using an automated rating system that allowed users to score designs on a scale from 1 to 5, but it never occurred to them that they had a real company. "It was just a hobby, a way for people to get their artwork out," Nickell says. By 2002, the hobby had surpassed $100,000 worth of T-shirts and attracted more than 10,000 community members, mostly artists in their teens and 20s. Even so, Nickell, DeHart, and Kalmikoff -- who joined the company that year -- spent much of their time doing freelance Web design to pay the bills.
Shortly after founding the company, Nickell and DeHart began awarding small cash prizes to the artists whose T-shirts were selected. Initially the prizes were $100 per winning design, but they gradually climbed to $2,500, plus reprint fees. But the appeal of Threadless to artists has never had much to do with getting paid. "It wasn't so much the money," says artist Glenn Jones, who won $150 in a contest in 2004, at age 29. "It was how cool it was to get your shirts printed." Young illustrators had few outlets in which to display their art, and within a few years of the launch, Threadless had acquired a sort of American Idol cachet. It was where unknown designers went to make their names.
This rabid engagement propelled the company through four years of phenomenal growth, beginning around 2004. The user base grew tenfold, from 70,000 members at the end of 2004 to more than 700,000 today. Sales in 2006 hit $18 million -- with profits of roughly $6 million. In 2007, growth continued at more than 200 percent, with similar margins. Though Nickell refuses to disclose the exact revenue number -- perhaps because he now counts Insight Venture Partners, a New York venture capital firm, as a minority shareholder -- it seems fair to assume that Threadless sold more than $30 million in T-shirts last year."

The numbers since the founding in 2000:
125: Number of submissions received by Threadless each day.
“Millions”: Dollars earned by selling T-shirts” not by hiring star designers but by asking anybody to design them.
Hundreds of thousands: Number of user voting each day.
6: Number of new T-shirt offerings per week.
1,500: Typical size of a batch of each new design.
2,000: Dollars paid to winning designers.
“Almost everything”: Number of items that sell out. (http://www.nytimes.com/2007/07/08/magazine/08wwln-consumed-t.html.)
