The pattern includes step-by-step written description: how to crochet the hat. I added video tutorial and the chart.

You can crochet with other yarn of your choice by similar yardage. If you want to get smaller size hat, please use hook 3.0 to 3.25 diameter. If you want to get smaller hat from bottоm to top, please work 23 rows insead 29 before decreasing.

I used almost 3 sceins (130 gr) of yarn.
