After I finished the blue shirt I went on to the white with metalic thread. After cutting it out, doing the darts and pressing, this is what happened!
This came from Mood in New York - I think I'll send them an email on this. I just got back from G Street and got some much nicer white on white Pima so I'm on to that instead. That is as soon as it's pretreated (it's currently in the washer).
