I have decorated it as you can see with some Celtic knot work, which is actually a bird animorph though the creature's head is actually covered by the bindings for the totem - I did these as eagle talons. I have not seen anyone do this before.
It might seem incongruous to be mixing Celtic imagery with a native American flute but there is an old Welsh legend that in 1170, Prince Madoc sailed off to explore the Western ocean and came back again a year or so later having discovered a rich land. He took a hundred or so settlers with him this time for his return to America and they were never seen again. The legend has it that they established a colony in South East USA but were eventually defeated by the locals. The survivors were absorbed into neighboring tribes - believed by many to be the Mandans, who use skin-covered coracles just like the Welsh ones. That might just be wishful thinking though.
