I'm sorry to hear that. As with all cotton shirts though, it's imperative that the shirt is tumble dried in low heat. Some people prefer to tumble dry with no heat and then hang them to dry. Dry your cotton shirts correctly and you'll never have a problem.
That being said, cotton is a very resistant fabric. (Hence the reason it's the most popular fabric in the world) We could print on 100% polyester, however, that material doesn't hold color very well and would limit our shirts to 1 - 2 colors. We like some Cotton / Polyester blends, but the color selection isn't great.
