Priming creativity for Tee-shirt design software

Increasingly people are designing their own tee-shirts. Companies such as Zazzle provide software online for people to design the fronts and backs of tee-shirts. Zazzle prints the design on the shirts and ships the product to the designer. The interface assumes that when a customer arrives for the first time on a site, they have a clear vision of the design they would like to create. For this reason, Zazzle.com primes for creativity are limited, using simple verbal encouragement such as "Get started!" And encouraging simple actions such as "put a picture on it" and "write on it."
