Used to have a shirt that an old girlfriend made for me,was kinda porn, and 'pretty' at the same time.
wasn't an iron on, but made with applique (?) If you just glanced at it, it looked like a close up view of the center of a flower, but it was actualy a chest down 'between bellies' view of a couple having sex on a stool, both leaning away with their heads back. No 'organs' showing other then a nice pair.
Don't know how many people came up and said 'I like your shirt',or 'that's pretty', I normally got halfway through saying 'thanks, my girlfriend made it' before their jaws would drop.
My girlfriend at the time was a real artist, and sold some pretty impressive works. Living with her is wher I learned a lot of making molds, casting and so on.
