First attempt with size M was too tight and second attempt with size L was too big.

At third attempt I started with 2.5 mm needles and size M. I made only 2 rows back and forth before I started k1 p1 rib.

I tried to knit chart with needles 4 mm, but it looked not good out. I ripped again and tried needles 3.5 mm. It was much better looking.

With 3.5 mm needles body of hat was way too big. I ripped it again to the ribbing. Now I will try to knit size S after ribbing and I will use size 3 mm needles.

After all these problems I got what I wanted. I love this hat.
