Ordered the 8'x10 size rug. Actually measures 8' x 10'6".  Having owned numerous Penrock rugs, I was prepared for the natural stretch that occurs.  I was a bit surprised that the large size rug would move as much as a small one would even with 2 legs of my couch placed upon it.  I ordered a felt pad immediately which solved most of the movement problem.  The rug is on my honey colored wood floors and blue/gray painted walls pull more color out of the rug.  Be prepared for sole loosening of some of the "rags", but a quick stitch can solve the issue.
