From Holly’s Blog:
I have worked this hat a ton of times, but have not worked every hat in every size, every pattern. I would love for you to post your pics of your finished objects here and of course, if there is a mistake, please let me know :)
I don’t mind if you make this hat to sell, but would like credit for the pattern. Please contact me at firstname.lastname@example.org for more info about this. Thanks so much!
