This is a beautiful, quality pillow.  As others have stated, it actually measures 20x20, not 18x18 - that was fine for us!  We ended up keeping it in our weekend home as it had more of an Indian design, than a tribal feel - it didn't pair with mudcloth or Moroccan prints at all, but looks very nice on a plain sofa against hardwood floors.  The pattern is on one side only and has beautiful woven detail. Also quite comfortable.
