I found a free Capucine hat pattern by Adela Illichmanova that I really liked, but it is written for big yarn. I didn't have enough yarn to double it so decided to make a worsted version. I followed her pattern pretty much, with a bigger cast on and worked the whole thing, but the flaps were too close together in the back and it didn't work. So I ripped back a bit and added an insert that separated the flaps and put them in the right place. Adela's hat is really great, but if you like/need my version I put the pattern on Ravelry in my project notes.
