This is officially NOT a coronet, but members of the Order of the Laurel in the SCA are allowed to wear a Laurel wreath if they wish.
This was commissioned for a friend. This is not how I had hopped it would turn out. I will be doing another for him, but he waited so long for this one I will send it to him so he has something now. It is a bit over 23 inches around, cut and painted leather.
