You have it better than we did. It was soak in white vinegar and salt water to set. It did work. I found a shirt with some of my own artwork on it from a long time ago. It was worn quite a bit years ago, and the artwork is still there in one piece. It might only be a tad fainter, but it hasn't run or anything like that. I also don't sort clothes when I wash so mistreatment hasn't killed it.
