This is a thinner carpet than expected. It has a high and low nap to the rug and I believe the height was measured from the high nap. The low nap is much like a sisal carpet. Certainly it has a lot of character, without a lot of wool shedding. The ends seem to curl up. I keep rolling the ends under to get the carpet to lie flat.. this may take some time, yet it seems like it is working. Much different from most rugs out there and the color is awesome and softer than wool.
