This is a fun knit that flew by pretty fast. I used a size 2 us circular needle. The pattern is an adult size but size of the hat and needle size can easily be adjusted by taking away some of the chart counts. I used 3 different colors for the hat. And have plenty more yarn to make another. Sorry don’t have an exact yardage. I hope you enjoy it and I can’t wait to see what you all come up with..
