I KNOW there are other completionists out there besides me; we all want to know all the furniture plans. There have been times where I've seen one I didn't know in a kiosk; offered to trade a new blue morrowind or dwarven plan that (according to my MM data) was double the price of the one they were selling, and still had them say no thanks.
So why don't people want to trade?
