On Wikipedia: Threadless is a community-centered online apparel store run by skinnyCorp, since 2000. Co-founders Jake Nickell and Jacob DeHart started the company with $1,000 in seed money after entering an Internet t-shirt design contest. Members of the Threadless community submit t-shirt designs online and the designs are then put to a public vote. A small percentage of submitted designs are selected for printing and sold through an online store. Creators of the winning designs receive a prize of cash and store credit.
