Like how the brim is, not the actual back to the hat. If someone can find a (free) pattern or preferably a video on how to crochet this, please list it!

Also, If it is a pattern i appreciate it but if you can tell me how a pattern works? Like how to read one cause im new to crocheting but i really would love to make a hat like that!
