Three of these blocks look like they're 1930's Schiaparelli inspired. It's hard to see the hats themselves, of course I had to do it in black wool and I took pictures at night. . At any rate they're cute. They look like "not knitted" Mad Caps.
I'll trim the caps un-Schiaparelli like and repost.. The fourth block is a 1950's half hat, it looks more like a beret. That one was a little fussy I'll redo that one in velour and wire the edge next time.
