Did you ever find where to purchase wood fibre? I just found a woman in Indianapolis that has a shop that sells them, but I cannot locate an address for her. She had an article on Profitfrog.com called The Future in Fibre Flowers; her name is Euna Douglass. If you find more information on her shop, I would appreciate hearing from you.
I used to manage a hobby shop in the 60's that carried Formosan Wood Fiber & that's where I learned to make flowers out of them. I still have a few corsages that I made back then. They look pretty good considering their age! The most realistic ones I made were gardenias & orchids.
Good luck!
