Found this on the Eflytyer site. Not one that gets much attention; pretty vanilla pattern compared to some of his other stuff, like the Ausable Wulff or Bomber, but in these colors it would make a decent hecuba (fall drake). Pattern calls for barred dun variant, of which I have none; 2 feather combo will suffice.
