Learned a long time ago that the skin off of the facing edge of a good size feather from a duck, goose, turkey or similar bird makes an excellent 'quill type' body. Has anyone else used this material? A good way to get it is to soak the feather for a short time. Put a small notch with a razor at the top of the feather skin. Grasp the lower piece of the feather skin and peel down. You may have to remove some inner pulp.
Who's used this material?
