This is a relatively easy pattern. The size can be adjusted by using a smaller or larger hook. It was made for a friend and I thought I would share it with you. :) If you have any questions, just let me know! I have seen there have been problems with the sizing for this hat. I used a 5.5 mm hook and it worked fine for an adult hat, but if that doesn’t work, you can increase your hook size or add another row of increase. I hope this helps!
