Anyone ever dye any shirts or sweatshirts? Like one base color? I have a gray shirt and somehow it came out fo the wash with very large blrown blotches on the front, it almost seems as if bleech got on it but I'm not sure how. I'm now wanting to just dye the entire shirt white. 1.) Do they have white clothing dye. 2.) If it is bleech on it, will it dye that white w/ the rest of the shirt. 3.) Does kmart sell anything like this?
