Gotta like them Rattan Bows...
Dean Torges has a place listed on his web site for Rattan.
Bamboo and Rattan Works, up in New Jersey I believe.
I ordered a couple of pieces from them a month or so ago.
They cut it to order.
Wound up with enough stock for Four kids bows and One 50+# adult bow.
Good looking stuff...
Now I just need to wag a bunch of projects (including the Rattan) over to a buddies shop to run it all through his bandsaw.

Cool Thread!
