I looked through many different pictures and patterns for sale and free. I did my own calculations and sizing. As Always! Came up with something I like.

On the inside of the band I did the slip stitch chain around the edges. It created less stretchy edge that hugs to the head, like stay-stitching.
Two buttons to insure snug fitting on different heads.

Flower is three-tier, crocheted.

Very quick and joyful project with instant gratification.
I will write the pattern later, if get interest in it.
