After getting the sections of the coronet put together, I tried it on and found that it was just a little too big. This was about what I expected, and I was just glad that it hadn’t turned out too small. I attempted to incorporate some padding when I sewed the leather binding on the bottom edge, but that turned out to be too fiddly to accomplish. Instead, I left the leather band unpadded and built a padded bolster out of cotton quilt batting covered in blue linen.
The bottom edge of the bolster is sewn around a piece of cotton rope, to form a shelf for the bottom edge of the coronet to sit on.
It’s still a bit fiddly to get it on, since the bolster is not attached, but once in place it is very stable.
