Rug Layering

I recently purchased a cow skin for my living area and thought all would be right with the world when it arrived (lol).  Don't get me wrong, I LOVE it.  But as I see it sitting on the ground, I can't help but wonder if it needs something else.  It's just sort of "floating" there.  Looking online, I've seen a lot of homes where rugs are layered and that makes me wonder if that could work for me.  I used to think that look was cluttered but looking at these pics, I'm thinking it maybe not. Hmmm.....

What about you?  Would you ever try layering rugs?
