Listen Graphic designer,
Just adobe illustrator cs3, take only 15 or 30minute and use your creativity, make a t shirt design. Now listen,
Do not copy paste anything from the other t shirt design site or I will report to odesk against you. I need unique sample and must be professional. Deadline next 48 hour. Mail me the graphics. Send me two version of the design, one .png for review and other the vector .ai
If you are real good designer, use some upfront. I will pay you $300 for this.
