Couple of questions: How much you got into that hat? And, will anyone else ever notice that imperfection?
I'd notice it too, if it were mine, and it would bug me. Can the ribbon be persuaded to come down that eighth of an inch without restitching it? You know, just kind of push it down a touch? The thread should have a bit of "give," I'd think.
Oh, BTW, nice lid. Wear it in health. If I lived in LA, I wouldn't be seen without it, at least during Daylight Saving Time.
