I read in the submission guidelines that the resolution of your picture has to be submitted at 72dpi and no more than 845 pixels wide and 445 pixels tall. I complete my designs in high res (300dpi), but when I shrink it down it becomes blurry.
Is the 72 dpi version just so the people at Threadless can give it a once over?
Also, anyone know how to avoid it becoming blurry? I'm probably making a totally n00b mistake, hehe.
