1. The 8' round rug is actually 7'5" to 7'6" - pretty big difference which was an annoyance to me especially at $450, but I'm not going to send it back. 
2. The ivory color is pretty true to the photos. I was a little dubious when I opened the package because the back side really shows the grey/tan threads a lot, but it's pretty unnoticeable on the top side and I'd still call it a true ivory. 
3. The uniformity of the knots/bumps is not as consistent in the photos online, and the gaps between knots are a little more than in the photos, but I still like the rug a lot. Really ties the room together, you know?
4 stars, just wish it was a true 8' diameter for the price and the several months I waited for it to come back in stock. I included some photos.
