Just visited an arborist friend in Indiana. He pointed out that he still has a nice size piece of artwork that was made by a retired school teacher, a customer we both had in common, in Beaverton, Oregon. She has passed-on now, but her name was Violet Frost Farr. She collected maple seeds and cut the winged parts off to make the bird feathers. Large seeds for large feathers, and small seeds like Japanese maple for small feathers. Smaller framed pieces were made too, of little birds. Sure wish more people could learn this art.
