Every queen needs a round, metal hat, or "crown". This one is technically a 'coronet' as it does not close in the middle. The queen is Titania, queen of the faeries, daughter of Titans, and fittingly, her crown is made of titanium. The parts were designed using Autodesk Inventor and fabricated with a CNC waterjet cutter, in the traditional craftwork of olde. At TechShop.
Traditionally, faerie crowns are forged in a volcano. If a volcano is unavailable, you can purchase .035 sheet titanium from a number of online suppliers. For a 22" circumference head, you will need a sheet 7.5" x 19." Titanium is not essential to the construction, you can use steel or aluminum. That is, if you fear not to offend the faerie queen.
