I did the ribbing first ""10" or what ever measure your cercumference of your head.
I knit using knook hook 5mm.
I knit 'till "5" not included the ribbing then I decrease until starting the tail pretty simple.
chain 70 for cercumference, DC all around,chain 2 turn ur work, 2 fp & 2 BP that's the blue.
Teal color same chain 70, DC round, then 2 fp, 2 dc, just repeat until you reach the wide u want. then connect each end.
