So Blue, Blue, Blue Feather Hatband. This Feather Hat Accessory will give a flare to any hat. I hand glue Sky Blue Rhinestones to each individual 'polka dot' of the Black-Blue Guinea Feathers. They are interlaced with iridescent light blue fluffy Marabou and Dark Blue Turkey Feathers. The feathers are attached to a 24" adjustable silk band. The band has Velcro closures which allow easy installation and removal, no damage to the hat. Adorn your cowboy hat, fedora, derby or just any hat! Feathers are durable and lasting for year after year. How about wearing this one to a Blues Festival?
