I just finished another sock monkey hat! This time I have to take notes. I struggled a bit with the size. This is made for a 3-6 mos old so I used a g hook. ended 48 hdc across and did 14 rounds. The first one I did was 51 hdc and it fit my niece perfectly. (and it was also 14 rounds) Sorry, I am mostly making these notes for me. But I love it! It turned out perfect!
