I was surprised by how thick this rug is, which is great, because the thickness helps to hide one particular blemish. When I walk on the rug barefoot, I can feel tiny hard lumps underneath my toes. When I dig into the pile to find out what they are, I find these hard, brittle white blobs down on the bottom of the rug. Mostly around the size of... uncooked Israsli couscous. I can break the lumps off from the bottom of the rug with my fingernails, and sometimes a little wool comes with it. I smooth the surrounding wool over to cover the tiny little bare spot, and the rug looks unblemished. Is this white stuff adhesive? It reminds me of dried joint compound, for any of you home renovators out there. Once in awhile I sit on the rug to see how many of these things I can dig out. Would probably take several months to a year until they are all gone, because they are everywhere -- every few square inches. So, the rug looks nice, if you don't get too close to it, and I got it for a good price -- but I guess you get what you pay for. These hard white things are not something you would find paying more than discount prices.
