This little one is more of a headband than a crown, but don't tell her that. She's a tiny princess and she still cares about appearances.
A number of years back, I saw a painting of Diana, in which she was wearing a crown that was also a set of horns. I loved it. Folks had been asking for tiaras and crowns for years, and all the sudden, I wanted to make them. So I began making them. That's the whole story.
These crowns are flexible. Will fit pretty much all adult heads. They stay on quite well just by their own natural springiness, but we've also drilled holes at the end, just in case you want a ribbon or pins or other extra security (highly recommended if you will be upside down at any point while wearing them). Not intended as a toy for children- just as a toy for adults who may or may not be grown up. Your call.
