We purchased the largest size to cover our decorative concrete overlay basement floor to add warmth and color to the space.  The blue is deeper than royal, just shy of navy.  The raised pattern adds depth and a plush feel in a light tan (slighter darker than ivory) color.   We used this over a recycled jute pad that will resist mildew.  After 1-2 weeks of play by my kids, a good vacuuming is needed because the rug sheds, as other reviewers mentioned.  Shedding is more noticeable because the ivory fluff gets on the blue areas and is highly visible.  Great price for wool.

Pros: Color, size, thickness
Cons: Shedding
