• I have tried so hard to get the creases out of mine, including ironing it with some clothes on top to keep it from melting. At this point I’m convinced nothing will work other than actually flying it outside for an extended period of time, which unfortunately isn’t really safe here.

    I’d guess this is why this is so common. Our flags are wrinkly because it’s often not safe enough for us to fly them in the wind.

    • I think it’s a case of explanation after the fact, but I always liked the idea that the creases signify the time its spent in the closet.

      You could also try hanging it up when you take a hot shower or steaming it to get the creases out if you care.
