In preparation for making my wire hat reproduction, I did a little research to find images of hats fashions of the era. This would help me to determine how the hat should sit on the head, how high the crown should be, and how wide the brim was. The book, "Vintage Hats & Bonnets 1770-1970" by Susan Langley was indispensable. I also found some lovely images online.
After toying with brim and crown sizes, I created a mock-up from black posterboard and tried it on to check the fit. Then I began creating the wire frame from rayon wrapped millinery wire, using my brim pattern as a base on which to build the frame. Tomorrow the frame will be completed and I will begin covering it with fabric.
