The Hydrangea - Wide Ivory Grosgrain RibbonWoven with raffia made from all natural palm tree leaves. The Hydrangea sun hat is the only hat I make that does not feature brass grommets, instead the ribbon is woven through the raffia. You can interchange your ribbon, but be careful to do so gentlyas to not unravel the raffia. The great thing about The Hydrangea is that the ribbon can be untied to adjust the hat size. The ribbon is designed to sit on top of the hat brim, this hat is not designed
