so i do this airbrushing stuff, and at least a dozen times a day i get asked if the paint fades. the answer is "not much . . . if you take care of it right".
the right way to to iron or heat press the shirt before wearing the first time, then when washing turn inside out, wash in cold water, and line dry.
but who really does that? i sure as hell don't. i make shirts, iron them, then abuse them like crazy. inside out, paint side out, hot water, cold water, soiled setting, and always always throw them in the drier. sure, i don't care as much because i can just make a new one, but let's just call it an experiment.
so here's a shirt i made for my dear husband in 2009:
now, after 2 years of being worn and abused at least once a week, this is how it looks:
so, in summery, the paint does stay.
