This hat started out being a different design with the loops joined.  So it ended up like this with the short loops not joined and six lampwork glass beads hanging from longer loops.  I made the crown loops a little shorter.  Being able to change a design in the making is the advantage of crochet over knitting, which I like too.  This hat is made of 100% superwash merino wool.  I would say it fits head sizes between 20" to 21".  You can style like you want.  One of a color.
