Did not like the steep arc on the pattern I found. Tore apart one of my old hats, similar to the tan one in my prior posting on hats and compared the pattern to the hat proportions I liked.
The brim pieces are 2 different sizes. The first two pictures are of one piece. Quite different. The third picture shows the other piece that almost matches the pattern.
The side piece is VERY different.
And the corresponding changes in the top piece. The back part is longer, to match the sharper and longer curve of the prior piece.
I’m planning on on creating a new pattern from the hat parts and build a second test hat.
I also found another free pattern at Urbandon. The arc looks like it’s also pretty steep, but there is nice information on sizing, fabric and construction.
