I love handmade rugs. I love that, at first, they look symmetrical and perfectly ordered, but, as you get yaed ti them, you discover that they are full of human flaws in the pattern. I love the depth of colour, and the variety.
I've acquired several (well, one large, which started the addiction, and several small), and the colours are almost irrelevant, because I can always find something or somewhere to match.
Mine are Bokharan, not Persian, but I imagine they're similar in how you live with them. It's better to suction vacuum them by switching the beaters off, but mine are in high traffic areas, so I leave the beaters on. But you must avoid the edges , especially if they are fringed, as the beaters will damage the edges. One was 2ndhand andhad been badly stored so it was smelly. I sprinkled it with bicarb, left it for a day, then vacced. Turned it over, repeated on the other side. Did this several times over a couple of weeks, and it does not smell. Actually it smells of wool, but it's not offensive.
I've spilt things on them and toilet-trained the dc, and they have always come up clean again. The one that on the living room is wearing badly, because the feet of people sitting on the sofas scuff it constantly. But that's the only place I cvan have it (it was in the hall in our previous place) and I'd rather use it, enjoy it, and wear it out, than not.
