Near the end of my post about my 15th century horned headdress I mentioned that one of the embellishing items would be a large brooch.
Well, here’s the post about that brooch!

Most of the paintings showing this style of hat shows it adorned by a large central jewel/brooch/etc. Once my hat was nearly done, I dug into my costume jewelery, but button box, my jewelery supplies.. and nothing really felt RIGHT. I figured instead I would need to make/assemble something.
